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.

All of these films share one commonality, that being a kind of emotional center that humanizes a cast of monsters.

A film of deceptively outspoken contemporary relevance, this is cinema at its most alert, alarming and alive.
