I love this movie! Yes, you can argue that the book wasn't met with the movie, but you have to relize that this movie was made in 2008, So the book was probably like that when the movie was first made. The intensity really added more of the suspense, and to people who read the book do know everything does end well, and even though your expectations weren't met, you have to know your expectations will not always be the same from movie to book. Overall this is a great movie. i recomend to be an age where you can handle someone dying and the lights going on and off.
