Lack of good storyline.

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.

By the time the dramatic fireworks start popping off, each one feels earned.
