5. Monster's Inc. Power Play
Boo - the little girl who finds monsters more funny than frightening finds herself in a magical land of Monsters! When it's discovered that a child's laugh is far more powerful than screams, Monster's Inc. shifts gears and goes into the stand up comedy business instead of using the old reliable scare-tactics. The fallacy in this particular Disney film is that Boo laughs and giggles quite frequently throughout her adventure without causing a power spike. Filmmakers admitted the inconsistency saying it proved to offer too many challenges if they followed this particular rule from the beginning of the movie.
