If you've seen either Black Christmas or Halloween, there's nothing new here: the hyped-up score keeps telling us we ought to be scared, but the suspense feels mechanical and fake.

You know a horror movie's in trouble when the fake scares outweigh the real ones.

I can't help feeling that this updating could have been a little more imaginative -- the only wrinkle on the basic plot is that it uses mobile phones.

There's something nostalgic and comforting about a teen-oriented 2000s studio horror movie, but I wouldn't say that "good" is an adjective to toss in there to describe this.
