Do you mean it's better than DVC and should be made into a film?
I thought it much more exciting, fast moving book than DVC, and although I'm able to suspend belief for the sake of fiction, I did find the character's escape at the end just a little implausible. Actually, I don't suspect too much belief in the case of either of these books, because I have had my reservations about the Christian church for many years now.
As for the film, I believe it's currently in production. Can't wait!!
I loved DVC but preferred Angels & Demons. I read it just after returning from a holiday in Rome so I knew all the places which made it even more exciting. It's fiction so who cares if it's real or not? A film would have to tone down many things so wouldn't be anything like as good as the book.
