Great visuals, story delivers no surprises

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.

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

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