This whole argument of movie vs. ride concept is hollow when you try to explain Splash Mountain or Big Thunder Mountain. One is based on a movie that Disney hasn't released in two generations. Big Thunder simply has a fictional backstory. Park representation is purely concept and entertainment driven. If it's a Disney movie, that's just icing on the cake!
Perhaps 10-20 years ago maybe, but not in this current phase. The Disney of today is looking for quick, easily recognizable characters and stories to capitalize on.
