In structure, acting quality, and thematic sophistication, this subversive black-and-white comedy by Alex Ross Perry represents a step up from his 2009 debut feature, Impolex. He gives a deadpan performance as a neurotic nebbish, and cowriter Carlen Altman plays his peevish sister, who nags him into accompanying her on a road trip to retrieve her stuff from her ex-boyfriend’s pad. Along the way they lodge at a motel so conservative that, in order to share a room, they’re obliged to impersonate a married couple; the incestuous overtones of this charade foreshadow Perry’s perverse riff on happy endings, when the siblings take to bed to resolve their differences. As a formal exercise the film shows daring, but it’s hardly entertainment.
