I honestly don't have all that much to say about this movie other than that it was a blast. Nazi zombies! In the snow! Nonsensical plot! Very funny stuff!
The two movies that come to mind as related to this one are The Descent, for the nature element - although Dead Snow doesn't do as much with it, there is an avalanche scene that could have been pushed a lot further. It seems curious to me to have a zombie movie that simultaneously pits the protagonists against nature itself. It kind of highlights the strange non-naturalness of zombies, not to mention the fact that really, nature is way more badass than any monster. Though I guess the humans do triumph over it, sort of.
It also sort of makes one think of Shaun of the Dead, mostly for the whole zombie movie that self-consciously references zombie movies aspect. This is actually something that bears thinking about, in that it seems increasingly common. Is this the sign of a genre dying out, that it becomes a kind of accumulation of references while still repeating the same old tricks? Or is it a sign of its perseverance, an impressive registering of a long noble heritage, and the fact that even though the audience pretty much knows exactly what's gonna happen from the get-go, it's still enjoyable to watch? Has fright simply transmogrified into new forms? Are we more afraid of terrorists than monsters?
Actually, there's another interesting point there, in that some would say that it's old school American horror that's died out, whereas Japanese horror, for instance, is going strong (or at least it was a few years ago - the fad seems to have passed now). So it's interesting that this movie is a clear throwback to American cinema - especially given that it's apparently one of the first Norwegian horror flicks, a rare specimen.
Oh - one weird aspect of Dead Snow is its obsession with poop. There's a big focus on intestines. And there's an outhouse scene that's just gross. Is this its bold, original take? Zombie film - now with Nazis and poop!
Anyhow. Entertaining movie.
