Are the IPs at least ones that mostly fit? Stuff like Inside Out (Imagination/WOL), Big Hero Six (Innovations), Ratatouille (France), Mary Poppins (U.K.), and Mulan (China) could actually fit at least as well as Three Cabelleros and Nemo do (not that those rides are great, but their IPs fit).Almost everything proposed as a new build is IP. For better or for worse. Some is very substantial. I've said it elsewhere EPCOT Center is dead. Let's just hope Epcot v3 is better than v2 ended up.
I'd say America is a bad example. Both Hall of Presidents and American Adventure do a decent enough job of it. Far older countries would be much harder, obviously, but it could still be done. Maelstrom attempted to do it for Norway. Impressions de France, O Canada, and Reflections of China don't seem to have brought tons of controversy. Obviously movies are different, but the same principles could be brought to a ride. The trick is to focus on an aspect of a culture instead of the entire culture. Most represented countries could have a ride about their folklore and fairy tales instead of their culture in general.And that's what the problem is, on the cultural sensitivity front. No matter what they pick as a "basic introduction" would be controversial at this point. As respectful as it may be done, no country/nationality wants to be boiled down to pretty much anything. Just imagine it from an American perspective - how would we feel if Japan had an "American Ride" - do you think we could really come to a satisfying list of show scenes that would "represent" us?
