The main thing Dead Snow wants you to know is that it's a splatter film about Nazi zombies. You like zombies, and Nazis add kitsch value, so you're sold. But once you get past the relative novelty of it (they're ZOMBIES, but they're also NAZIS!!), Dead Snow is only so-so. The only thing that separates it from the zombie movies you've already seen is that it's in Norwegian.
It's from director Tommy Wirkola, who, with co-writer Stig Frode Henriksen, had a huge hit in Norway with the 2007 Tarantino parody Kill Buljo. Dead Snow offers more proof of Wirkola's fondness for Tarantino, and you get the feeling he's seen plenty of Sam Raimi and George Romero, too. Those are all good ingredients, but without some kind of new spice all you're doing is serving leftovers.
Hungry now? Good. Let's talk about flesh-eating zombies. These ones are Nazi officers and soldiers whose frozen bodies, long hidden beneath the snow of Norway's hinterlands, have now been reanimated for reasons that Wirkola barely bothers to explain. Their victims are a group of college students who have trekked to a remote cabin for a weekend of wintertime merriment.
