I'm giving it a 5 star review for a couple of reasons. I personally loved the actors, thought they did a great job. There were parts of this movie that literally made me jump off my seat. Since it was midnight when it ended, I had to watch a 30 minute comedy before I went to bed. No way was I going upstairs with those last images in my head!
My only negatives would be the amount of dark scenes, there were times it was hard to tell just what was going on.
I would still grab a big bowl of popcorn and sit down for this one, preferable with someone else....why be scared alone!
