Future World was always divided in half this way; the eastern half featured the lengthy “hard science” style pavilions with heavy narrations. The western half featured the more whimsical, freeform, and organic pavilions. Even from 1982, the west half of FW had water features and flowing, curvy elements whilst the east half is dry and utilized clean lines and angles. And eventually thrill rides.
The renaming simply allows each area of the park to be that much stronger and better defined. Now it doesn’t matter if The Land doesn’t have synergy with something on the other side of the park because they aren’t as much a part of the same overall theme.
I just don’t see how anyone can see this as anything but a win for EPCOT.
Would you rather have the park as we’ve known it from about 2003? Or would you rather see the most unique park in the world continue to grow and change as it was always intended to?
I don't understand why you think these are the only 2 options.
Renaming Future World because the theme doesn't permit the intrusion of Comic Book Superheroes is
not the park "growing and changing as it was always intended to". It's growing and changing in ways it was decidedly
not intended to, or they wouldn't have had to break up the land into three and change the theme to do it.
Your post seems to be somewhat at odds with itself - in the first paragraph you cite (accurately) the dichotomy of Future World East and West, but in the second you suggest that the Land was subject to synergy with the attractions across the park . . . which, for the record, never happened in either the best
or worst days of Future World.
Future World's theme was never so limiting that nothing exciting and amazing could be done with it. They just chose not to for the last 25~ years. Disney ran the place into the ground in the 90's, let the Festivals prop it up for the 2000's, strung it along in the 2010's and then looked and said "We have to DO something, nobody likes this anymore!" . . . well, duh, guys. You let it fall to pieces. But the pieces themselves weren't bad - pick them up and build something new with them! It would be easy, and if well done you'd have a great park, new attractions,
and a unified vision.
But again, their interest is no longer in
having a unified vision. It's in using the Marvel characters however they can in Florida to prop up sagging numbers. Animal Kingdom got a new hit ride in 2017, DHS in 2019, MK is seemingly evergreen . . . and then there's EPCOT.
It's a shortcut. They aren't interested in making the park "stronger and better defined" or they'd actually be doing that. Instead they're putting a giant, Marvel-shaped pot under the leaky roof and calling it fixed. And it's a big pot, so it'll hold a lot of water. But the roof's still leaking and they don't
really care to fix it.
