Epcot obviously need's an update. I know many people here are before my time,but I think that Epcot's Future World need's to become an actual future world like it was in 82. I really think that even though learning is fun and Epcot is, people my age hate it because it is still simi stuck in the 90's. I call for a major overhaul of Future World and the only thing that stay's is Spaceship Earth , Mission Space , and Test Track 2.0
And this is some of the problem Disney has in dealing with Future World. Mission: Space is a fun ride, and I like it, but many of us who remember the Epcot Center of the late 80s/early 90s would say it isn't an Epcot attraction. To us, Epcot is for experiences, not just rides. Horizons was an experience. M:S is a ride, although a good one.
So, I'll agree with your major overhaul. But Living with the Land stays. Spaceship Earth stays but gets is descent finished. Test Track 2.0 sounds like it might be heading back towards an experience, so ill give it a shot. M:S would go. Energy should retain its grandeur and scope, but be overhauled to be serious again. Move the dinosaurs to Dinoland and use that space for several animatronic show scenes. Nemo/Seas needs to have some focus put back on the actual fish. Soarin stays awaiting its new film that should "move" the attraction to World Showcase (new entryway to same theater). A new movie and show come to the Land. Imagination gets a whole new ride that ends a spiral moving ramp up to the second floor where we put what we just saw into use ourselves. Give us a weather pavilion with Stormrider and Aquatopia from TDS, plus an exhibit floor with weather-related interactive elements.
Of course, that's a lot to wish for.
