The best part of the movie is the ending credits

Rating: Null/10 (21 March 2009)

I'm giving this movie two stars out of ten, for two reasons: one, the premise was good, and a good movie could have been made out of it -definitely, not the case here. And two, the ending credits, which were actually much creepier and more suggestive than all the movie in its entirety.
It would be long and pointless to note all that is completely wrong in "30 days of night". To name a few reasons not to watch this piece of nonsense, let's say it's boring, pretentious -especially in the depiction of the "creatures", for they aren't really vampires, more on that later-, packed with bad, bad acting; completely devoid of any tension or atmosphere; absolutely not scary (it doesn't even have that couple of predictable yet satisfying scares that even the cheapest horror movies offer); and laughable in too many a scene.
The story makes no sense at all. We are never told a story; rather, we are witnesses to a number of sequences that are closer to action than to what a vampire movie should be. Another big problem with this movie is its complete lack of pace or of build-up: we never feel that we are watching a group of humans trying to survive a vampire attack for 30 days of night, with all the psychological content and depth that that would imply; the passing of time is marked by such a simple device as telling the viewer that it is "Day 1", "Day 18" or whatever. The characters never look or really act any different on day 18 than they do at the beginning. We never get the feeling that more than one or two days have passed. All the characters are barely sketched, they are interchangeable and we never feel, nor care about their plight.
If all of that weren't enough, this movie throws all of the cinematic and popular vampiric mythology out of the window. The creatures that raid the little Alaskan village are a mix of zombies and ghouls, and they are ugly rather than scary. In fact, it wouldn't be unreasonable to watch it as if the creatures were actually regular wrongdoers or human bad guys instead of monsters.
Those are only a few of the many flaws about "30 days of night", but I believe they are enough to put anyone off watching it... indefinitely.
