First it must be stated that this picture is quite far removed from the book. Having said that, I have been trying to decide if I would have liked the movie had I not read the book. My conclusion is fair. There is simply too much information and nuance that is not in the movie. The interaction between Vittoria and Robert, leaving out MAJOR character's, etc. It seemed to be "Angels and Demons" meets one of the latter day Bourne pictures. Read the book. It's much better.
