Sadly Over-hyped

This movie was so-so. It had it's moments, but wasn't the greatest.

This is a must-see and one of the best documentaries - and films - of this year.

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.
