Based on the cover art I mistakenly thought that DEAD SNOW was going to be a kick ass horror movie. It wasn't. In fact, for the first 30 minutes or so nothing happened at all. Finally the Nazi zombies show up and they're silly, not scary. Overall, if you have low expectations and are just looking for a good horror movie to get drunk to and watch with a bunch of friends then DEAD SNOW would be an alright choice, but not the best choice.
There is one moment that shows a quick glimpse of how this film could have actually been good: the head in the window. That scene was great and if this movie had actually been serious instead of a lame comedy then it would have been scary as fuck, but instead it was quickly forgotten in the mess of stupid jokes. Example: zombie getting hit by tree limb while riding the snowmobile. Hahahaha, stupid. The comedy highlight of the film was when the dude got bit and then chopped his own arm off. If the entire movie had been as hilarious as that two minute scene then it would have been a classic. Here's hoping that if they make a sequel that it will be better.
