What makes it different from others?

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.

If you're interested in the topic at hand, you should just watch it and judge yourself because the reviews have gone very biased by people that didn't even watch it and just hate (or love) the creator. I liked it, it was well written, narrated, and directed and it was about a topic that interests me.

One of the best movies of the year! Incredible from the beginning to the end.
