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.

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?

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