I think if you loved the book series you will love the movie. Even though the movie did not adhere to many of the lines used in the book, I believe the screenplay helped move the story along without getting too deep. The one thing that I am not sure about is if you had not read the book if it would have delivered as a good movie on its own. But having read all the books, it brings alot of richness to the movie experience. I would recommend reading the book and then seeing the movie for the full effect.
