Goodbye Lover is a smarmy mix of laughs and thrills that stars Patricia Arquette and Dermot Mulroney as a couple from hell. She sells expensive real estate; he's an ad exec. She's fucking his brother (Don Johnson); he's fucking his assistant (Mary-Louise Parker). When one of this motley crew is murdered, the investigation is headed by a detective (Ellen DeGeneres) who's made her own share of moral compromises. Director Roland Joffe, whose career has reached the heights of The Killing Fields and the career low of Demi Moore's The Scarlet Letter, is in Demi territory here. Besides, any movie in which Don Johnson gives the best performance is its own worst enemy.
