Hello Llegoz. Good to have you here.
I don't see negativity here as often as I see comments on what could be improved. Granted, some people get nitpicky and fail to see the big picture but more often than not the recurring issues are legitimate concerns about a park we love and would like to see restored to looking and operating it's best while providing the premium experience that the guest pays for.
Here's some of my thoughts;
Tomorrowland; Most of that land needs a revamp. Innoventions is a good idea but just not well executed, and never really has been - time for a new show. The top floor above the Starcade has been unused real estate for more than a decade. The Peoplemover track sits and rots - every time I go to Disneyland I overhear guests and even kids who never knew what the PM or Rocket Rods was commenting on the track and how it looks broken. The Observatron sits broken where the Astro Orbitor should be. Captain EO was nice to have back for a short time but it can't stay forever. Fix what is broken and improve what is there!
I will agree that the merchandising seems to be more generic than it used to be, and that there seems to be a wavering focus on how it related to the theming from land to land. I wouldn't expect to find Jack Skellington in the Star Trader, but there he is, and I can find the same stuff in Le Bat en Rouge across the park. I've heard it said that APers like myself are traditionally not big into buying the merch because we're there more often, but if there were more unique and diverse offerings, who knows? I buy the occasional shirt if it's something I've never seen before.
I think Disney has been doing a good job with the California Adventure makeover, and only a few small spots in that park remain that could really use some improvement, namely over in Hollywood Land with consistency of quality and styling. But Buena Vista Street is very well done (though I don't agree with the recent window change-up of certain storefronts), and Cars Land is excellent. My wife and I can actually spend an entire day in DCA now.
Lastly, I would like to see a return to/more focus in the park overall on creating unique attractions and experiences that create adventures that are not based on movies, or only loosely based on movies (i.e. Space Mountain, Haunted Mansion, Big Thunder, etc. - you know, classic Disney magic) I don't mind a movie-based attraction if it's done well, but when i was a kid I was always impressed by how Disney would create these amazing, unique adventures that were like nothing else you'd ever seen, and nothing else you would ever see anywhere else. I'd imagine that these days, investing in a major attraction that doesn't have a tie-in to a motion picture would be more of a risk, but I also think that if an attraction or a ride is truly good enough to stand on it's own, then why shouldn't it be attempted?
I'm a huge fan of the parks, and I always have been. It's a challenge to keep the park relevant and viable for today's younger generations while still retaining classic Disney signatures and staples, but I believe it can be done if a direct connection to the fan base is carefully cultivated and maintained.
