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

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

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.

It's a movie as timely as it is provocative and amazingly, for much of its running time, it is weirdly funny.
