Krampus operates like a feature-length Twilight Zone episode: Take some lightly sketched stock characters (Adam Scott as drinky dad, Toni Collette as uptight mom, David Koechner as Randy Quaid), thrust them into slowly escalating supernatural peril, and watch the dramatic gears grind out a morbidly satisfying conclusion. While it lacks the zany spark that animates Gremlins or the deconstructionist bent of something like Cabin in the Woods, Krampus is a solid exercise in form and function. Also, the creature designs are super creepy (and mostly teeth). If you see one movie this winter about a goat-hoofed anti-Santa, make it Krampus. by Ben Coleman
