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 those movie experiences that is so good it makes you realize you've been grading everything else on a curve.

After playing with our expectations, this turns out to be a very different sort of film.

The film's masterful storytelling did its job. The message was clear. No need to overdo.
