Seemingly made as a spite against all of the safe, cheerful, child-friendly Christmas movies released each year, Bad Santa is an unapologetically profane comedy that aims to shock with its decided bad taste. Nonetheless, in its own lewd and lascivious manner, it holds an underlying sweetness surrounded by a bitter wrapping. Director Terry Zwigoff (Ghost World) takes a sort of demonic glee in skewering the holiday films of old with one that holds the power of scarring children for life. It's rated R for a reason, folks. It's also very funny.
