Lack of good storyline.

The film makes a home in your brain and the only cure is to see it again.

There is, somehow, an interesting story here, as well as some good acting. There are also some good scenes

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.
