Damien, I haven't seen the movie, but reception has not been good. Although it did perform surprisingly well in its first week of release, word of mouth has not been kind to it. It looks like it'll fall to fifth place this weekend.
I don't know if you have followed the whole ordeal, but there's actually two versions of this movie: the first one was directed by Paul Schrader and is supposedly a "psychological drama/thriller". Apparently this was not what the executives at the movie company wanted, so they fired Schrader, hired Finland's own Renny Harlin and started again from scratch, script rewrites and all. This "gorier and scarier" version is the one in theaters currently, the original version is supposed to get a straight to DVD release soon. Although I'm not the biggest Exorcist fan (I've seen the first one and thought it was pretty alright), it would be fun to compare the two versions...
Anyway, moving on to my latest seen flicks:
Absolon
Surprisingly well made B-movie starring everyone's favourite Scotsman Christopher Lambert, some washed up British model with a big chest, Hellboy Ron Perlman and Lou Diamond Philips, who's doing his best Agent Smith impression through most of the movie. It's a futuristic thriller set in a world where most of earth's population has been wiped out by a virus and the remaining population are slaves to the cure that must be taken on a regular basis, Absolon. Lambert is a cop investigating the death of the creator of Absolon. After that it degenerates into the usual conspiracy "the government controls us and anyone questioning the status quo must be stopped" thriller, with Diamond being the main bad guy (doing his best Agent Smith impression, as I already mentioned).
The story does have its holes, but overall a pretty enjoyable movie.
Identity
Great thriller starring John Cusack and Ray Liotta. Ten strangers end up at a motel in the middle of nowhere. Then they start dying one by one. Think "Psycho" meats "Ten little indians". It starts of as your typical "whodunnit", but the twist ending is...wow. It screws with your mind! Highly recommened movie. Apparently the trailer completely spoils the movie, so don't watch it if you plan on seeing the flick...
Donnie Darko
Another great movie, even if I think I need to watch it a few times before I'll understand what's going on

Donnie Darko (Jake Gyllenhaal) is your average teenager. Well, apart from the fact that a jet engine falls out of nowhere into his bedroom, and it surely would have killed him, had he not been out on the yard talking to a giant rabbit who's telling him the world will end in 28 days. And then it gets even weirder. If you like weird movies, this one is for you!
