Bad Santa is fantastic.
Billy Bob Thorton plays an over-the top hostile drunk who works as Santa in department stores each year waiting to steal from the safe on Christmas Eve. He works with a sober dwarf who cases the store, and who constantly has to shove Santa into shape. The story involves the people that Santa meets on a particular heist in Arizona, which includes a relationship with a woman who has a Santa fetish, and a strange, deadpan, chubby boy. Santa's unapologetic bad cheer never wavers, and yet, of course, in the end it's a heartwarming movie with a sweetness that isn't at all gooey.
