People are voting emotionally.

Blending excellent reporting and strong storytelling, this is a disturbing film truly stranger than fiction

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

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.
