Anyone seen this? The previews look pretty cool. From what I've read, it's one of the better horror films in a long time, not relying on CG or crazy gore effects to "scare" people. Instead, it's subtle, minimal, and actually, well, scary. Which would be nice, for a change, from a recent horror film. In any case, I wanna take this really cool girl to see it and I'm wondering if it's worthwhile. Thoughts?
