Other than Magic Kingdom, I feel like all of the parks are suffering from serious issues. Disney doesn't seem to know what to do with the parks other than to throw in attractions based on the movies. Now, at least in Magic Kingdom most of the time it has made sense, albeit other times not, like Stitch's Great Escape (how the heck has that not been closed yet? Didn't the Stitch fad wear off?0
Definitely, EPCOT is having a major identity crisis. Future World is full of pavilions that need help. Most of them do not even reflect the original intents, and those that do desperately need updating, like Journey into Imagination and to a lesser extent Ellen's Energy Adventure. Now they are throwing Frozen into Norway where they know perfectly well it only very loosely fits, but they just had to cram it in. A meet and greet I'm OK with, and they could even make the ride something special by theming it as a tour of Norway guided by Frozen characters - we all know that's not gonna be the case.
Hollywood Studios is in a similar distressed position, they clearly do not know what to do with it at this point, closing the landmark Backlot attraction pretty much put the nail in the coffin for the concept of this park. They need to just start over with a new idea because honestly for the money you pay to enter the park there is not anything close to enough to do to justify it, and year by year, it becomes less and less. Again, many of the attractions have nothing to do with the park's concept or theme (Rock n Roller Coaster comes to mind).
Animal Kingdom, the one park that was relatively untouched with the "based on movie" nonsense (other than the Bug's Life show but at least that kind of fits), is getting Avatarland. I never saw Avatar, so I can't speak to whether it is a good movie or not. As far as I can tell though, it has absolutely nothing to do with Animal Kingdom in essence. They are just putting it where they have tons of room, it seems like, and to attract people to the park.
If all four parks are just going to be a mismosh of ideas, with no real theme and purpose, that's fine, but you may as well just call them Magic Kingdom A, B, C and D. I am tired of movie based tie-ins for every new attraction. What was the last attraction Disney opened that had nothing to do with a movie, recent or otherwise? Movie tie-in attractions have always been an important PORTION of their offerings, but it is no longer a portion, it's the whole pie.
If Disney wants to successfully continue to charge so much to enter their parks they need to set themselves apart and make the parks unique and special, not just a bunch of movie tie-in rides that scream "cash grab"! Inventing original stories to base attractions on is what Disney was known for. It was what set them apart. Iconic rides at the Magic Kingdom - Jungle Cruise, Small World, Carousel of Progress, to name a few, are based on nothing other than Disney's creativity and originality, not a movie tie in. Can we go back to that?
