The difference is that, today, the animated characters are used EVERYWHERE, in nearly every land, to the point where all the Disney parks are becoming more and more bland, dumbed-down and uninspiring. Tiana didn’t start this; when Splash Mtn. was first announced, many fans hated the idea of a cartoon-based attraction outside of Fantasyland. And I gotta say, that did seem to be the first crack in the dam. I don’t like the way DL’s Fantasyland later expanded past the front of the castle. Epcot and both coasts’ Tomorrowlands get more childish and cartoonified with each passing year.
One of the reasons Islands of Adventure has become my favorite Florida park is because its lands remain so refreshingly focused and unique. You won’t see a “We’re Back” or a “Land Before Time” attraction in Jurassic Park just because “hey, it’s dinosaurs—it fits, right?”
