It's the perfect pitch: Gaslight meets Memento with a splash of Gone Girl. So goes this tale of a woman (Nicole Kidman) who wakes up every morning with no memory, and begins to suspect that the man (Colin Firth) who claims to be her long-time husband might be hiding something. If only she could remember ... and that nice doctor (Mark Cross) is helping out. Yet despite a good cast and a delicious marriage-thriller premise, Rowan Joffe's adaptation of S.J. Watson's novel fails to get a good grip. Maybe it's the generic suburban London setting, or the baroque plot that starts to feel more half-baked as it unfolds, but what should have been a nervy, twisty thriller felt perfunctory. Save this one for home viewing.
