Hallam Foe (the infinitely endearing Jamie Bell) is a creepy teenager who wears a badger pelt, hangs out in a tree house, and spies on people with binoculars. If those people are having sex, he's not above swooping down from his leafy bough on a zip wire to terrorize them. Writer-director David Mackenzie mines Hallam's eccentricities not just for oddball comedy but for outré sweetness, which creates a gently, but deeply, moral atmosphere. The film never punishes him for discovering that his freakier tendencies are simply who he is. (See movie times, www.thestranger.com, for details.)
