A Studio Ghibli land of some sort could definately work in USJ, but probably not in the US.
The hype for most of Dreamworks stuff is so meh for me as their track record is just poor compared to Pixar. I guess if it makes enough money it might be worth a ride, but a lot of the Dreamworks/Illumination stuff just feels forced when it comes to rides because you have the IP and gotta use it compared to the quality.
First statement is false....hints why they can charge 60 dollar passes for movies that are over ten years old.

with HTTYD going to IOA. That only leaves the Middle Kingdom with Po or Shrek for fourth park for unique landscapes. I don't think Croods and Caveman translate to theme parks very well unless it is the Flintstones like which the show and the movie don't portray at all
