The film makes a home in your brain and the only cure is to see it again.

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

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.

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