paranormal activity. definitely freaked me no matter how much i tried to deny it. the first version i watched of it was the "original" ending with - SPOILER ALERT! - the girl sitting next to the bed all day until the police show up. the image of her standing in place next to the bed for hours made the hair stand up on the back of my neck. in context, that is one of the most frightening images i've ever seen in a movie, but once it happened the first time (about half way through), i knew exactly how the movie was going to end.
