I had read the book years ago when my children were younger so I wanted to also see the movie. I didn't remember much of the plot at all so everything was a suprise. All I could say at the end was "wow!' and "interesting!" I saw the movie with my daughter now 22; she works at the cinema where there was an advance showing. We both enjoyed it. It's one of those movies you keep thinking about afterwards. I love when that happens :-).
