People are voting emotionally.

A brilliant film that helped define a genre

I gave this film a 9 out of 10, because it was exactly what I expected it to be.

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.
