It's entirely possible that sending the audience out feeling lousy was intentional

I am only giving this movie a 1 for the great cast, though I can't imagine what any of them were thinking. This movie was horrible

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

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.
