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.

Go in cold, and you're likely to emerge with your blood boiling. This has to be seen to be believed.

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

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