I read the Angels & Demons book a long time ago when it first came out and Dan Brown is an amazing writer. When I heard the movie was coming out in May, I decided to re-read the book. The movie diverted from the book in many instances, so I honestly wish I hadn't re-read the book so recently, as I feel I would not have remembered a lot of the key details and would not have been distracted by the diversions in the story line as much. Overall the movie was very good, Tom Hanks is an amazing actor and I will definitely buy the movie when it comes out on DVD.
