Nazis zombies? Who doesn’t want to sign up for that, especially as they feed on oversexed medical students Easter vacationing in the Norwegian Alps? If you tamp down your expectations — those gaping plot holes are dangerous! — there is a storm of scary fun to be had in this Scandinavian splatterfest. Conveniently, the vacationers include a movie junkie (Jeppe Beck Laursen) who points out the flaws in other horror flicks. I suspect director Tommy Wirkola has been feeding on Sam Raimi’s The Evil Dead for years now. You won’t mind much. The blood looks crazy creepy in the snow.
