I enjoyed the book immensely however, I was somewhat disappointed in the fact that the connection between science and religion was fairly moot in the movie. I would like to have see more emphasis on why the anti-matter was created, not just to blow up the Vatican.
I understand that the movie could not go as in depth as the book as far as plot but I really wish the sinister character would have been more sinister than nerd....the book presents him as very dark, disturbed and satanic-like.
Overall the movie by itself was entertaining, but based on the book I was a bit disappointed.
