It's okay.. bit confusing though due to kind of "flashbacks" going on throughout the movie.
I found it stupidly funny most of the way through, mostly due to a very comical start where a guy falls, there are a few moments that are purely there to make people jump out of their seats (er, actually I wont say any more).
Sarah Michelle Gellar is, as always lovley though.
It reminded me strongly of the ring - just in a house this time.
It would've been a great movie, if the plot wasnt so predictable as it follows the same lines of most other similer movies (er, if that makes sence). Still, its worth seeing.. Just I wouldnt get excited about it
