S21: The Khmer Rouge Killing Machine

Pahn arrives at a coolly devastating picture of a regime that claimed more than 2 million lives.

The efforts of victims and victimizers to come to terms with historical trauma are admirable, but the film is too tough-minded to espouse a facile discourse of "healing" in the face of genocide driven by ideology run amok.

A haunting look at the historical amnesia that envelops countries or regimes after officially sanctioned barbarism.

Offers one of the most powerful and unforgettable looks at evil.
