Not only did the movie go along with the book in a majority of aspects, it stayed true to character personality. The ending was at a great point of the book as well. The ending of a climactic scene but enough to entice audiences to come back for the second one. Although I would say it is graphic. But that is also in the book so I am not by any means complaining. I just feel some should know the ending is the reason for the PG 13 rating.
