Lack of good storyline.

Expected more

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

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.
