OMG me and my friends went last night too and stayed up till 4 A.M. talking about it. I was upset that most of what was in the commercials wasn't in the movie. But, what was in the movie was freakin' epic. This is now my all-time favorite thriller other than The Rite.
The girl who played Katie was really good in playing the part. I was smiling the whole time I watched it, and I admit I let out a few squeals myself.
