Maintence and safety. Glad they refurbed the Junge Cruise before the falls fell on someone!
TLC. I loved the additions to the Haunted Mansion, Pirates, Tiki Room, and Jungle Cruise! DL even got a new train!
Monster's Inc. While this ride feels a bit cheap and cartoony, I think it fits the kiddie studios theme already established by the Muppets and is, without a doubt, an improvement over Super Star Limo.
The DL Fireworks are completely awesome and I forgive them for making crowding worse.
Tomorrowland. I enjoyed seeing Azimo, and the "new" color for the land helps it feel less like the bottom of a trash can. It was also great to see bands return to the Tomorrowland Terrace stage, even if it's still called Club Buzz.
Space Mountain returned! This is great, but the entrance feels confused, unlike it's speed ramp days. Still, it's back!
Buzz is a very cheap, low imagination ride that is off theme in Tomorrowland. While any increase in capacity is good for Disneyland and this space was unused, this ride is a net negative for the park. Ride it a few times and the flat track and boring rooms will make you long for a fantasyland ride.
While it's great to see the subs returning, why Nemo? I guess since the ride's capacity is low, they want to make sure the lines don't get too long with repeat business. It's interesting to note the best and longest lasting rides are not clearly themed to a single movie.
