The first half was good... then it got kinda slow. The effects were good, and I thought the crazy guy with the spetsnaz was kinda cool. The noise the things made was kinda creepy too.
We went to the 9pm showing on a kinda stormy night. I looked over at one point and she was balled up in the corner of her seat. My first thought was to put my hand on her knee to make sure she was ok, but I could tell she was in attack mode and I may lose that hand. After we got out she said "I was terrified." I didn't think it was a very scary movie, but then again, I've never been scared by a movie (i'm still looking for one that'll scare me though).
All in all, it was worth the $10... the dinner after was better though.
