Blending excellent reporting and strong storytelling, this is a disturbing film truly stranger than fiction

At first rather annoying in its heavy emphasis on reenactments, this movie ultimately proves fascinating, simply because the complicated, highly dramatic tale it tells still almost defies belief.

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

One of the best movies of the year! Incredible from the beginning to the end.
