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

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.

After playing with our expectations, this turns out to be a very different sort of film.

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