A.O. Scott, film critic for the New York Times, reviews "The Wind that Shakes the Barley" a new film by Ken Loach starring Cillian Murphy.. . .But in watching “The Wind That Shakes the Barley,” his new film (which won the top prize at Cannes last year), it is possible to appreciate both Mr. Loach’s passion and his sense of nuance. Set in Ireland in the 1920s, the film paints history in stark colors and observes as they blur and bleed. Mr. Loach and Paul Laverty, the gifted screenwriter with whom he regularly collaborates, leave no doubt as to who the villains are in this tale. . .Radical though he is, Mr. Loach is hardly a romantic, and the deep humanism that informs his best work — a category in which “The Wind That Shakes the Barley” surely belongs — is insulated from sentimentality by the sense that history is a long, bruising fight, a chronicle of compromise and defeat as well as of tentative triumph and provisional hope. He is also, as anyone steeped in the history of the modern left must be, acquainted with the factionalism and disunity that bedevils those who see themselves on the side of the angels. . ."
