I watched Dead Snow at its premiere, but various distractions prevented me from writing on it untill now. Also, I'm lazy, but that's nothing new. Let me just start off by saying that Dead Snow is several various kinds of awesome, although not every kind of imaginable awesome, there's still a few unclaimed veins of awesome that just *might* be refined.
Anyway, the zombies did more than jog, in fact they were quite agile, although they sadly were suffering from the henchman duel syndrome, or if you will, a strong dislike to actually swarm ye' olde intrepid adventurers and murder and/or eat them, like any sane strenght-in-numbers group actually would. Of course, it makes for better fatalities when they're so polite to run up to our heroes one by one to get slaughtered, but it feels a bit odd when some poor sod's time is up and the zombies overcome their stormtrooper syndrome and multistab said poor sod.
And yes, the zombies do stab people, and blow people up with grenades, and such. Of course, it's a fantastic opportunity for the people behind the camera to show off their mad period weapons knowledge, but it somewhat defies the whole "savage beast vs. inteligent and scared man"-thing. Still, said grenade usage is used to end one of the most unnerving zombie munchage scenes I can remember to have seen. In a comedy horror flick this may seem strange, but I've never seen first-person Death by Zombie, so it was particularly jarring.
At any rate, Dead Snow is a definite recomendation, provided you can get your mits on an eventual DVD release. Of course, for Norwegians, it's simpler. In fact, in that case, why are you reading this? Shoo, go watch Dead Snow.
