Mark Romanek's adaptation of Kazuo Ishiguro's low-key sci-fi novel lends a chilly creepiness to its setting, a boarding school where clones (including Carey Mulligan, Keira Knightley, and Andrew Garfield) are raised and harvested for their organs. But the film doesn't know how to deal with the basic interiority of its most crucial themes. The amount of time the children spend at their boarding school, growing indoctrinated with and accustomed to the purpose of their existence, is given short shrift, and as a result a key concept—how horrific circumstances can come to seem perfectly normal—is jostled to the side by the bigger question of why the hell these attractive, healthy teenagers don't just run away. by Alison Hallett
