Krampus

Overworked dad Tom (Adam Scott), uptight mom Sarah (Toni Collette), teenage daughter Beth (Stefania LaVie Owen), and young, Christmas-loving son Max (Emjay Anthony) host their loud, cynical extended family. After Max's obnoxious cousins embarrass him by reading his heartfelt letter to Santa aloud at dinner, a furious Max tears up the letter and declares he hates his family and Christmas. Tearing up the letter breaks the festive bond protecting the household, plunging the neighborhood into a fierce, supernatural blizzard and cutting off all power. Krampus and his terrifying holiday helpers—including malevolent gingerbread men, a demonic jack-in-the-box, evil elves, and a carnivorous teddy bear—begin hunting and picking off the family one by one.
