Stone walls do not a prison make, nor does a promising concept necessarily guarantee a satisfying film. “Camp X-Ray” has a great idea behind it — a young female soldier assigned guard duty at Guantanamo Bay forms a kinship with one of the incarcerated Muslims — but first-time writer-director Peter Sattler doesn’t go anywhere interesting with that notion.
Neither the soldier nor the detainee (never call them “prisoners,” we’re told early, lest the the Geneva Convention apply) emerges as a particularly memorable character, and while the ongoing situation at Gitmo is a fertile topic for discussion, Sattler doesn’t bring much to the conversation.
