It's not great by any means, but it's a pretty good movie that didn't leave me filled with regret for investing time in it.

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.

Very good movie overall, highly recommended. Most of the negative reviews don't have any merit and are all pollitically based. Give this movie a chance at least, and it might give you a different perspective.
