The basic problem is the screen play. Do we care about these people? I don't think so. The running gag about Nicky resembling Halle Berry runs tired after the second time it's mentioned. Even the book that Quincy writes makes no sense.
Jamie Foxx is about the only pretext for spending almost an hour and a half with this film. He is an interesting performer no matter what he is doing. The beautiful Gabrielle Union is fine as Nicky, but there is no heat between Quincy and her. The rest of the cast struggles to make this comedy succeed.
Watch it at your own risk.
