I've never even been tempted to watch "Bad Santa", just not my type of humor/film. Best Christmas movie? Can I pick "Die Hard"? If not, it is a dead heat between "It's a Wonderful Life" and "Ben-Hur" (the 1959 version). And I'd like to claim "lack of bias points" on the basis of selecting Ben-Hur despite the fact I am an atheist.
