Here are some really well thought out and interesting critisms about DCA...I would have never been able to put them this way. I just found it really interesting. YOu can either read them in this post or go here to the actual site:
A large number of people on the internet, including many in the main stream media, have criticised the park in general as well as specific aspects of it.
One complaint is that the California theme is not a clever or engaging one, and furthermore not one that interests Californians. Since Californians account for a very large proportion of visitors to Disneyland Resort (60%, according to research) this is a major drawback.
It was designed to be a living showcase of California past and present, for tourists who have come to the Golden State.
Allied to this is the criticism that the park is "not Disney enough." Rather than capitalize on the success of Disneyland itself and Disney's successful products, very little of the park (especially at opening time) had much to do with Disney themes. This was especially apparent when comparing the park to the other park Disney had opened the same year, Tokyo Disney Sea, which was praised for its attention to detail and the overall quality "Disney touch" the park possessed, although ironically The Walt Disney Company doesn't even own the park. Many felt this "Disney touch" was noticeably absent in DCA. Similar criticisms were said about Epcot, Disney's second Florida park in Walt Disney World, when it opened in 1982.
A November 2002 Marketwatch.com article reported that the cost of building Disney's California Adventure was $650 million. Disney did spend $1.4 billion to convert the area from just Disneyland Park to a resort, but the other $750 million was spent on the Downtown Disney mall, the Grand Californian Hotel, and other resort improvements. John Cora, who was vice president in charge of Resort Development when DCA was being built said in the article that Disney's highest priority in developing the park was to keep costs down.
The Imagineers who designed Disney's California Adventure had a limited theme to work with. The history of California is set in stone, and design creativity was limited at risk of being historically inaccurate. Compare this to Disneyland's design, where Imagineers were allowed to create practically anything they could imagine, maintaining the appropriate theme.
 Emphasis on shops and food, not on attractions
Disney's California Adventure is also rather light on rides and attractions in general, and a number of the rides that have been created are limited in their capacity (chiefly Soarin' Over California). Disney management insisted that the park be built to a budget 20% under what the firm would have previously considered adequate, and it is the view of detractors that the savings have come largely out of the parts of the park that are considered "loss leaders"-- the attractions, in other words. In their view, Disney spent much more time and effort on the shops and restaurants than they did on the attractions, though the latter is most peoples' main reason to visit.
On the other hand, Disney's California Adventure does have as many or more attractions than other Disney theme parks around the country such as Disney's Animal Kingdom and Disney-MGM Studios in Florida (both are several years older than Disneyland Resort's second gate). It was the inevitable comparison to its neighbor, the 60-attractions filled Disneyland, that makes California Adventure's offerings seem minuscule since it offers only about half as many attractions.
One major difference between Disneyland and its sister park is that California Adventure serves alcohol. Many restaurants offer beer; the Pacific Wharf area has both a beer truck and a margarita stand. The Golden Vine Winery offers wine tasting, and as part of the Ariel's Grotto restaurant, the Cove Bar has a large selection of cocktails, along with beer and wine. Disney tried to get a major beer company to sponsor the park, but failed to do so. A deal was made with San Diego based Karl Strauss Brewing Company to be the official beer supplier of the park and sponsors the beer truck in the Pacific Wharf area. It also has seven different types of their beer on tap at the Cove Bar.

The admission price was highly criticized upon launch. Disney charged separate admission for Disney's California Adventure at a rate equal to the Disneyland entry fee. To many guests, the price (then $43) was better spent on the larger, more attraction-loaded, and proven formula just across the entry plaza -- the original Disneyland. Disney's California Adventure seemed to offer less value for money than the original park.
Disney also announced that its guests who held Annual Passports for Disneyland would not get entry to its new park. A Two-Park Passport would be available, but at a much higher rate. In fact, Disney suspended sales of all its annual passes just before the opening, and did not restart sales for three months. It was widely rumored that Disney was planning to either scrap the popular Annual Passport program altogether, or to withdraw single-park passes and force everyone to buy more expensive two-park passes.
Disney refused to offer admission discounts to its high-end opening restaurant sponsors (Mondavi, Wolfgang Puck), forcing sponsor restaurant patrons to pay full-admission-price just to access the restaurants (both of which ultimately failed).
With the unpopularity of Disney's California Adventure obvious soon after launch, none of this took place. The price differential between single park and two-park passes eroded, and eventually Disney merged the two, at the lower price, effectively giving entry to Disney's California Adventure to annual pass holders for no additional charge.
Although the park admission remains the same as Disneyland, the relative price for entrance has been drastically reduced by special promotions. The 2fer Ticket, which has been offered for many months in the last few years, allows Southern California residents to "Pay for Disneyland, get Disney's California Adventure Park for FREE!" (this is an exact quote that Disney uses in its marketing campaign for ticket sales), and other promotions such as one offering two "free" days to visitors from around the world planning to buy at least a three-day ticket are not uncommon. As two-fer tickets approach expiration, Disney's California Adventure becomes very busy and has on more than one occasion closed for capacity.
Unlike the original Disneyland, the only mode of transportation around the new park is on foot. There are no buses, trains, monorails, or vehicles of any kind available to the public. (The Disneyland Monorail passes over Disney's California Adventure, but does not stop there.) The park itself is actually much smaller than Disneyland, and so covering it by foot is not difficult.
Guests staying at the Disney's Grand Californian Hotel have their own entrance to the park. This entrance may also be used by guests of any of the three Disney owned hotels for first entry, and any park guest that wants to re-enter the park. A special entrance which used to be available to the guests that stay at Disney's Paradise Pier Hotel has been closed.
A large number of the original attractions were criticized as disappointing, including most of the attractions and restaurants in the Hollywood Backlot area as well as the Paradise Pier area which has been criticized as lackluster and generic. (In a number of cases, the Paradise Pier attractions are quite generic: Mulholland Madness is in fact an off-the-shelf Wild Mouse roller coaster with minimal theming, and a number of the others are equally standard.) At the same time, though, given that Paradise Pier is themed as a sort of sanitized, nostalgic version of an old-style seaside amusement park, the generic nature of some of the rides is a part of the area's theme.
One of the original Hollywood Backlot attractions was Superstar Limo; at the time it was the only dark ride in the entire park. Its plot revolved around the guest as a celebrity who has just arrived at Los Angeles International Airport, and who is taken for a ride through Hollywood in a limousine. The humor was based on inside jokes ("Madame Leota" from The Haunted Mansion makes a cameo appearance) and obsessed fans and paparazzi, and much of it very likely went over the heads of many guests. The attraction was criticized for crude sets and characters, and was the first attraction in the park to close. It was open for less than a year, and a Monsters, Inc.-based attraction was constructed in its place. Monsters, Inc. Mike & Sulley to the Rescue! opened on January 23, 2006, following its soft opening in late December 2005.
The Hyperion Theatre, also in the Hollywood Backlot area, initially opened with a show called Steps in Time. Contrary to the implications of its title, it was not based on Mary Poppins nor on any sort of Disney retrospective; critics generally regarded it as a waste of time, and, despite a last-minute rewrite, it quickly closed. It was first replaced with an abbreviated version of the Blast stage show, then with the current Aladdin show.
The Orange County Register mentioned Disney's California Adventure Park in an article listing the top 20 Business stories in the last 20 years on September 3rd, 2006. Disney's California Adventure was ranked the 6th top story, and said "California Adventure was doomed to a slow start from opening day in 2001. The gamble that atmosphere and dining would mask a shortage of rides was a flop."
 Attractions for small children
The park as first built had few attractions geared towards younger children, surprising those used to Disneyland's child-centric attitude. Currently, all of the attractions built for small children can be found in the a bug's land area, and there are few outside of this area: Monsters, Inc.:Mike & Sulley to the Rescue! Playhouse Disney, and Jumpin' Jellyfish. While on one hand this makes life easier for tired parents or grandparents who don't want to have to walk very far between attractions that their kids can ride, it's very inconvenient for parents who wish to experience more than just one tiny area of the park.
However it should be noted that California Adventure was originally designed to be more mature and adult themed than its sister Disneyland park.
 Changes since opening
Since opening, a large number of changes have been made to the park. A large proportion of the attractions and restaurants in the Hollywood Backlot area have been closed, and some re-opened with less-California, more-Disney themes. Most of the farm area at the center of the park has been rethemed upon the Fall 2002 opening of a nearby area for young children themed around Pixar's A Bug's Life movie (distributed and marketed by Disney.)
One of the first attempted "fixes" was the building of "Who Wants To Be A Millionaire - Play It!" attraction, which was a copy of the same attraction being offered at Disney-MGM Studios Park in Orlando. But Disney decided to not bring over the pre-show to the California version. The timing of the opening of the attraction was unfortunate, as it was scheduled for early September, 2001. The scheduled media opening was cancelled due to the aftermath of the September 11 attacks. It remained open until August 20, 2004, when it was closed to allow the labor costs to be shifted to other entertainment in the park. There was also the persistent rumor that the attraction was shuttered due to Annual Passholders repeatedly attempting to win the big prizes. (The sister Orlando attraction closed August of 2006.)
In 2002, the park added Disney's Aladdin: A Musical Spectacular to the Hyperion Theatre in its Hollywood area. The show has become a favorite for many, with a script and original lyrics that are high above the standard theme park fare. The effects are also impressive; children love to see Aladdin and Jasmine take flight right over their heads on the magic carpet. The show performances have been cut back, with the show dark two days a week during the summer and other peak periods (to allow the need for only one main cast). Also, the show tends to have smaller crowds as many regular park guests have seen it, and are not returning.
A number of restaurants operated by outside firms have closed or been taken over by Disney as their sponsors pulled out. One example is Avalon Cove on Paradise Pier, which was once operated by Wolfgang Puck; after he walked out on his contract, Disney converted it into Ariel's Grotto, a family restaurant where kids can dine with characters. Also, many restaurants that Disney operated when the park opened in 2001 are currently closed, including Hollywood & Dine, Lucky Fortune Cookery and the ABC Soap Opera Bistro.
Disney relaunched the well-known Main Street Electrical Parade, formerly at Disneyland Park, as Disney's Electrical Parade in Disney's California Adventure Park. This did not find favor among many Disney fans, who had been promised that the parade had been retired permanently (and who had purchased expensive commemorative items based on its permanent retirement, which were replicas of the parade's twinkling lights). However, guests generally welcomed the return of this thirty-year-old "California Classic," and still line up to see it. Disney's Electrical Parade is currently on hiatus, and will only perform for a few weeks during the peak Christmas and Easter times, before it comes back in late June for the summer of 2007.
Disney also attempted many different types of events to drum up business, but all have been cancelled. Some of the more publicized events were Fiesta Latina days, Super Soap Weekend (still offered at the Disney-MGM Studios at Walt Disney World), ABC Primetime Preview Weekends, Rockin' the Bay (a summer music series), and the X-Games Xperience.
On May 5, 2004, Disney's California Adventure Park opened the Twilight Zone: Tower of Terror attraction in the Hollywood Pictures Backlot area of the park. This attraction is similar to the ride of the same name at Disney-MGM Studios in Florida. This is a thrill ride, based on the premise of an elevator car falling free when the cable breaks. On its first weekend, it pushed Disney's California Adventure attendance to one of its highest points since the park's preview days.
As part of the Happiest Homecoming on Earth, Disney's California Adventure Park opened Turtle Talk with Crush based on the characters from Finding Nemo, and a replica of the attraction opened last year at The Living Seas at Epcot. This attraction features "living" character technology, where Crush interacts in real time with the guests in the theatre. Similar technology is also used to talk with Stitch in Innoventions in Tomorrowland. Also recently opened as part of the celebration is the brand new dark ride called Monsters, Inc. Mike & Sulley to the Rescue!, which occupies the venue formerly housing Superstar Limo.
On May 5th, 2005, Disney's California Adventure also premiered its new Disney's Block Party Bash parade. Unlike most Disney parades, the Block Party Bash is a very upbeat parade, that uses all non-Disney songs except for one Disney song. A specially recorded version of "Celebrate" plays as kids in colorfully clad costumes dance and show faces of enthusiasm. The parade stops at two different spots along the park's "performance corridor" and once in place, an 11 minute impromptu party begins (Weekends only in the off season). As of September 2006, Disney has decided to cut the performers from 120 to 80 and remove part of the Bug's Life portion, along with some minor parade units. However, the music, choreography, and 11-minute show stop will all remain the same; the only actual cuts being made to the show are in the physical "length" the show occupies along the parade route.
Disney's California Adventure Park newest show is a mobile song and dance routine themed after "High School Musical," the extremely popular Disney Channel original movie. The show features live singers and dancers performing versions of the movie's popular songs. The show takes place along the "performance corridor" with 2 stops, similar to Block Party Bash. Currently the show is offered Friday thru Tuesday, with additional showings to be offered on Peak weekdays and holidays. This event has a cast of about 20.
 Future Plans
It is important to note that much of this section is based on rumor and not fact. The Disney Company has not officially announced any of these plans.
It has been rumored that starting in 2005 the people at TDA began to brainstorm a major placemaking project for the park after the small placemaking project had worked so well for the Backlot Studios section of the Hollywood pictures backlot. The original project featured a major renovation of the current main entryway with the Golden Gate Bridge, the facades, murals, plaza, and sun fountain torn out and replaced with craftman style architecture similar to Disney's Grand Californian Hotel. The Plaza was planned to be rebuilt into a transportation center similar to the Main Street U.S.A. Vehicles. The point was to make it look as it had been when Walt Disney first arrived in the 1920's. Other projects would follow as more scenery and attractions would be added to other lands. There were several smaller ideas such as adding curbs to the streets.
That plan was later scrapped for a more extended project. Now, the newest project is to first, tear out the Route 6 section of Paradise Pier and replace it with a ride base on Cars featuring Lombard Street and would be part of the Bay Area District. This plan too, was thought to be scrapped, but a Disney concept art of a Cars themed attraction called "Carland", which looks similar to Epcot's Test Track, was recently leaked online . Although there is no confirmation on which Disney park the ride is intended for, it is possible it is the rumored Cars themed ride for DCA. Additionally the entire Pier area will be themed to Victorian. The Maliboomer attraction would become a Green Army Men attraction and would have its drops toned down. California Screamin would be villains-themed and the Sun Wheel was unknown what would become of it. Orange Stinger would be demolished and the Zephyr moved up the pier. The Placemaking project concerning the redo of Paradise Pier and the Bay Area Section as well as the Main Entry Area is set to be done by 2010. Construction is to begin after the opening of the Toy Story Mania Attraction(previously known as Midway Mania) in 2008.
According to Jim Hill Media, the Disney company doesn't own all of the land on which the former Disneyland parking lot--now California Adventure--is situated . Disney only controls the land through long-term leases from third parties. Although many of the leases aren't set to expire for a long time, issues regarding land ownership may hinder any further expansion of California Adventure.
Several accountants working for Disney, as well as outside observers have actually suggested demolishing the entire theme park and rebuilding it as the originally planned Westcot, or a variation of Tokyo Disney Sea, which would save the company money over time, and would make the company more money over time.
