What makes it different from others?

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

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.

Great movie. Not sure what people expected but I found it highly entertaining.
