From imdb: "Centers on a young girl who has been murdered and watches over her family - and her killer - from heaven. She must weigh her desire for vengeance against her desire for her family to heal."
I too, have read the book. I've heard that you shouldn't see the movie if you like the book. But, I'm a sucker for Mark Whalberg.
I'm looking forward to seeing Shutter Island that is opening this weekend. I think the book was the best book I have ever read. I hope the movie does it justice. If anyone sees it let me know what you think.
