Does it "fit" with EPCOT (or what it's supposed to be, anyway):
Frozen: Nope. Not at all, and probably the worst offender. Arendelle is not Norway. Being Norwegian inspired doesn't matter if the actual location is still fictional so I'm not really sure how they could make the IP work.
Ratatouille: Nope. It takes place in Paris, but the ride is just you running from danger. They could have made it work if they came up with a new concept - Remy takes you on a tour of Paris culture and cuisine, while dodging danger. Boom, done.
Nemo: Nope. The ride is just a recap of the film. They could have made it work by having it be, say, a field trip with Mr. Ray touring coral reefs or something.
Journey of Water: Not really. The edutainment value they attempted to shoe-horn in about the flow of water is superficial at best.
Guardians: Nope. They present what is basically a parody of an old school Epcot pavilion. If the actual ride had something of value to say it might be different, but instead you're just outrunning the bad guy.
Gran Fiesta Tour: Actually, yes! You're trying to find Donald, but Donald is too busy enjoying the sights and culture of Mexico. It's the first IP makeover and the only one they did right.
