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

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.
