The Wind That Shakes The Barley [DVD] 
Ken Loach's melodramatic attempt of using two Irish brothers who are at odds with one another to stir up drama proves to be a good formula here. This greatly adds to the watchability of a movie which gives a unique insight to the Irish Civil War. It shows the dark side of war, people's ordeal and how clash of political principles as well as rupture of human values and bonds pit brother against brother.
Lastly, visually the movie is a feast to eyes - from idyllic backdrops of Irish countryside to gloomy dankness of a prison cell, every scene is shot beautifully. For those who like docu-dramas and Ken Loach type of social realism, "Barley" is a must-see.
