What makes it different from others?

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

This movie feels like it was made purely to piss off people who want good shows

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.
