A taciturn 16-year-old (Gabe Nevins) in Portland, Oregon, accidentally causes the gruesome death of a security guard and tries to deal with the psychological consequences in Gus Van Sant’s 2007 adaptation of a novel by Blake Nelson. This has something to do with guilt, alienation, and the loss of virginity but a lot more to do with skateboarding, and the emotional disassociation is underlined with Nino Rota’s theme music from Amarcord and Juliet of the Spirits. (Van Sant is a compulsive hijacker of other people’s material, from his Psycho remake to his appropriation of Chimes at Midnight in My Own Private Idaho, but he never enhances or illuminates what he filches.) There’s some striking camerawork by Christopher Doyle (in 35-millimeter) and Rain Kathy Li (in Super-8), though this doesn’t alter the overall feeling of random, nihilistic drift. Elephant said much more about teenagers and said it better.
