good back-story, and good acting

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

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.

While it doesn't offer any answers, it both thrills and makes you think.
