The Wind That Shakes the Barley (2006)

Ireland is raked over the coals of internal strife after they drive the British from their shores.

Young Dr. Damien is recruited as a freedom fighter against a brutal and unforgiving British occupying army. Damien fights alongside his neighbours and his brother in an informal military force that must discipline itself to the point of executing traitors - their own friends and brothers. When victory is achieved, the nation is plunged even further division because of a disagreement of the terms of truce. More blood is shed.

There is no pleasure in watching this film aside from the sheer power and anguish expressed. The Wind that Shakes the Barely belongs on the shelf with other tragic classics.
