This is a pretty decent slasher trilogy in the making.
I saw the first "Cold Prey" and thought it was okay. It was kind of slow and the kills weren't that great but it was beautifully filmed, well- enough acted for a Swedish film, or maybe that's Norwegian, who knows, and it had an awesome twist ending with one of the best hardcore metal songs to the end credits I have ever heard. In many respects it was a lot like Halloween (1978).
"Cold Prey 2" is even better than the first. It keeps all the successful elements from the first movie (well shot, well acted, well-directed) but has more kills, more tension and less build-up which is good because really, I've seen it all before and unless your birthing some slasher narrative miracle of nature there really is no need to have protracted character development revolving around horny teens.
Actually I liked this one (#2) better because it takes place in a hospital, has fully mature adults who are way less happy and way less whiny than the annoying teens in the first movie and has way better kills and pacing.
By the way, Halloween 2 (1980) takes place in a hospital. Go figure.
