Really? I thought The Mist was pretty (very) bad (awful). The ending definately shocked me, in as much as I can not to this day find the words to describe how bad I thought it was.
Anyway, there was this film festival here last month, and I saw three "zombie movies". Quotations because two of them really are not zombie movies, despite the living dead being central to the plotlines. The only legitimate zombie flick was Dead Snow, the norwegian one about nazi zombies. I have heard a lot of complaints about that one, mainly that it does nothing but regurgitate tired horror cliches and I have to disagree. The movie is indeed full of cliches, but they are (nearly) all used flawlessly. It had some truly great scenes, was pretty funny, and the snowy mountains provided a great ambiance.
The other two movies both had great premises, and while I enjoyed both, they really were flawed films. Minor spoilers ahead meybe, but not really, just outlining the premises. The first one, Grace, is about a pregnant woman whose baby dies shortly before she gives birth. She carries the baby to term anyway, and miraculously the baby comes to life shortly after birth. We soon find out that the baby is special, and causes some unusual problems for the mother. My main complaint with this one is that it is really slow. Also, the extra characters were kind of plot device-y. But the movie features some pretty disturbing imagery. See it if you like the premise.
The final movie I'm going to talk about is called Deadgirl, and is about two highschool kids who find a bound girl in the basement of an abandoned mental institue. One decides to keep her as a sex slave. Then they find out she can't be killed. Wacky hijinks ensue. The story that is woven around this premise is a bit too high-school-drama for this to be a genuinely good movie, but iagain, if the premise sounds good to you, see it, for the perverse shock value. It has some excellent scenes and ideas.
