Tells a fascinating and unsettling true story, and does so well, without pretending to have all the answers.

A film of deceptively outspoken contemporary relevance, this is cinema at its most alert, alarming and alive.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

One of the most extraordinary films you will see this year. Take that as you want.
