Though Californication's third season featured the stubborn refusal to resolve longstanding plotlines, the season's fundamental problem was far more, er, shallow, than that. While fans of the show can likely find ways to enjoy, or at least overlook, Hank Moody's (David Duchovny) intense promiscuity in the first several seasons, it starts to wear thin by this stretch.
It doesn't help that many of the objects of his lust are the college students he's teaching. Although there was nothing illegal about what Professor Moody was doing, it's hard to root for a guy who's behaving this scummy with women this young. Moody's behavior while he was on staff in the English department was a low point, even for everyone's favorite sex-crazed writer. It can be fine drama to watch a man's wife and daughter stop believing in him, but it's harder when the audience stops believing in him too.
