Captivating throughout it's entirety, even though I had already watched the movie. I was craving more information, and although I didn't get a ton more, it helped fill in the gaps. As they say, the book is definitely better than the movie. I am more or less satisfied, although I still have lingering questions. But much like the way I feel about LOST, they are questions better left up to my own imagination and interpretations. 4 stars.
