Coming to Town (2006)

JoBeth is an 11-year-old girl who gets bullied at school. Desperate for help, she writes a letter to Santa Claus asking for revenge instead of toys and candy. Her wishes come true when, on Christmas eve, her enemies get a visit from an avenging, blood-thirsty Santa Claus and a couple of deranged, sadistic elves. By employing heavy artillery and extreme violence, JoBeth's bullies get their punishment and the Christmas spirit is restored.
