Good start, but then it gets ruined

Good concept, poorly executed.

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.
