Bad Santa stars Billy Bob Thornton as a pathetic, drunk loser who lives to drink himself into a stupor. His main sin is the three B's. Booze, Boobs and Buttfucking--- Billy Bob goes through the movie being a drunk mean to everyone he meets and somehow through meeting child (who insanely belives in Santa) he starts to redeem himself. Sure he's filthy and foul mouthed yet we feel sorry for him and want him to get on the road to sobriety. He tries hard to resist and in fact gets worse and worse throughout the whole movie. It's fun to watch such a pathetic character. I think it's enjoyable because no matter how much our lives suck, his is ten times worse.
