What makes it different from others?

It is a performances centric movie

This is ultimately a movie about the very bad things that can happen when we don't address our unease, when we just try to brush it off, whether that's to fit in or to preserve our self-image.

Great example of an old-fashioned, pure-at-heart escapist event movie that doesn't pretend to be anything that it's not and has boat loads of fun being its own ludicrous self.
