What makes it different from others?

it is the rare 'crazy' movie that actually has something to say.

a film so unique, intoxicating and bizarre that it not only demands another viewing, but is also forgivable as a satirical comedy where the jokes eventually take the back seat.

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.
