It was OK. I don't see why everyone loves it so much. It wasn't very smart or deep or well-directed.

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

All that we are seeing on the screen is happening with real people, real action sequences in the background, forcing the eye to watch as if we were there.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.
