Lack of good storyline.

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.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.
