"Goodbye Lover" is certainly unpredictable, but there is a catch: once you've figured out the movie's cynical attitude (every single character is a slimy cheat looking for the big bucks), the twists all fall into the same pattern and lose their impact. Ellen DeGeneres is particularly grating; Don Johnson, Mary Louise Parker and even Ray McKinnon come off better, because they are pleasingly understated. (**1/2)
