I had read the book three times before seeing the movie. I was hoping it would be as close to the book as The DaVinci Code was. Even though it was a good movie...comparing it to the book there were vast differences. Some of the suspense that was in the book was lost in the movie. And the big twist at the end of the book wasn't even revealed in the movie. So it was a great movie if I didn't read the book...But I still enjoyed the movie.
