This movies greatest strength is its original idea and the unique charms of Billy Bob Thornton. Thornton plays a wretch of a man in this movie, but still manages to be someone we kind of like and are kind of rooting for. Maybe he represents to communal Christmas id, the guy who says the s****y things of the season all of us are thinking but would never say, I don't know. Whatever it is, it works. I really don't think this movie would work with anyone else in the lead role. I also liked his chemistry with the kid in this movie. It's a bizarre and often hostile relationship, but it works. The movie isn't a laugh riot, hell it's really not that consistently funny even, but it does have an odd charm to it. Not a great movie, but strangely a very likable movie.
