This Movie Can Only Be Described With One Word.

Masterful Movie

It's fun, it's light, [but] it has a hard time when its tries to get heavy.

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.
