I decided my first review of this movie was inadequate. If you don't recall, it went like this:
Opening sequence - Damn creey.
The Rest - Meh.
I liked the movie. I really did. But it was more along the lines of Resident Evil than of The Exorcist. Not a great movie, but still thoroughly enjoyable. The movie, as you probably know, centers around a video tape that kills a person exactly seven days after he/she views it. The opening sequence shows two teenage girls having a sleepover, and one of them mentions it. The other one reveals she watched it a week ago. Then she dies. It's very creepy, especially if you're alone at night. Anyway, the main character is an investigative reporter whose son (who sees dead people) was very close to the dead girl. (They were cousins.) Rachel does some investigating, her friend watches it and helps with the investigating, her son watches it, and she does more investigating, until she finds out the whole story and how to make it not kill people.
The movie was pretty good, but I had a few problems. The characters were all pretty weak. We don't get any kind of feel for the relationship between Rachel and her son, and Rachel's motivation changes back and forth throughout the movie. In some scenes, she's driven by her emotions, and in other scenes, she's being very professional about everything. That would be understandable, except that her scene-by-scene motivations seem very arbitrary, almost as if it were an afterthought. It seems like everything was set up specifically to push her through the movie, which is normal, granted, but it still all looks very deliberate.
Overall, I dug the movie. It was entertaining and superficially satisfying, but it was certainly no Exorcist.
