Load of rubbish!!

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

The film's masterful storytelling did its job. The message was clear. No need to overdo.

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.
