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.

Unshakable, witty and deeply felt, the film will be paying emotional dividends for a long, long time.

The movie turns out to be a little better than the average. Starting from a romantic formula often seen in the cinema, it ends in the most predictable (and somewhat bland) way.
