Just finished watching Lovely Bones. I think it is quite possible that it is a brilliant movie. Creepy...yes...but that's part of what makes it brilliant. After watching it, I'm interested in what the book is like, but I'm not sure I want to experience that again. Just because it was brilliant doesn't mean I want to put myself through that in such depth as reading requires.
I was worried there for a bit that the ending wouldn't be satisfying, but it actually was quite satisfying indeed. Anyway, I think it's worth checking out. I think you'd be pleasantly surprised by the geniusness of it, but freaked out and unable to sleep for a few nights as well.
