Lack of good storyline.

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

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.
