Save your money for something good and enjoyable

In truth, there is barely enough story here to make a film.

Your blood may run cold, but you now find yourself pinioned to the story.

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.
