The concept is very EPCOT, but the aesthetic is 180° from '80s EPCOT, which was very stark with lots of concrete. I loved it in the '80s, but by the the mid-'90s it just felt cold and dated. So they added a bunch of brightly colored triangle tarps all over the place as a fix. By the millennium and "The Wand", the spine was an absolute thematic mess. It definitely needed an extreme makeover.
I think the location, being sort of in front of both The Land pavilion and The Seas pavilion, is also pretty much perfect. A very green place to get wet will be very popular for a good bit of the year here is steamy FL.
