Watched it with the wife last night, it was way better than I thought it would be. Very creepy atmosphere, that had me on the edge of my seat for pretty much the entire movie. Only a few things bugged me:
****SPOLIERS****
When she escaped from the mental institution, and all those cops were at the front desk, she jusy waved the gun in their direction, and they just let her walk out? Then it took them forever to get their shit together and go out after her.
She went after him from the mental institution. Why? I mean, I get that she wanted to be the one to stop him, but all those cops 'saw' what was going on, and I'd assume they had video cameras in the hallways. She could have just stayed there and let them deal with it. He didn't threaten to go after the girl until she chased him down outside.
Anyway, other than that, thought it was a pretty good movie.
