Lack of good storyline.

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.

It's a movie as timely as it is provocative and amazingly, for much of its running time, it is weirdly funny.

Very good movie overall, highly recommended. Most of the negative reviews don't have any merit and are all pollitically based. Give this movie a chance at least, and it might give you a different perspective.
