"We're all part of a formation," says Arthur's teacher at band practice. "Every person matters. Every step is in anticipation of the next." This statement becomes a credo for this haunting film, as events of the past weeks untangle. Director David Gordon Green (Pineapple Express) paints a sensual, haunted portrait of contemporary post-industrial America. This is a land where evangelical ideals mingle with furtive trysts in motel rooms. Where bleak winter scenes and dark interiors are warmed by the sensuality of first love. It's also a place where devotion turns to violence, and silence is interrupted by terse emotional outbursts. The characters who have fewer illusions about their lives -- like Arthur and his mom -- are rewarded. Those who are steeped in illusion suffer a grim fate. Could this be a cautionary tale for our time? Green is a director to watch, and fans will enjoy this cornerstone of his repertoire.
