Although it has its amusing moments, in eneral the plot does not convince.

I really wanted to like this movie. I feel terribly cynical trashing it, and that's why I'm giving it a middling 5. Actually, I'm giving it a 5 because there were some superb performances.

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

One of the most extraordinary films you will see this year. Take that as you want.
