My own thoughts on this I liked the Davinci Code . It was different , and a bit interesting , but what I ' m gathering in the comments here is that the book and movie had totally different endings ? When I first saw the movie trailer , I thought ' oooh , doomsday movie , but nothing is really going to happen because the good guys will win and everyone will continue on with their lives . ' So , for me , I ' m not really interested in seeing the movie because of the Hollywood clique ' Happily Ever Ending ', I mean , there ' s no point . The bad guys will lose , the good guys win , wash rinse and repeat and I think maybe Ron Howardthe producersexecutives are a bit stuck with that train of thought when it would have actually been refreshing and vastly unique for the good guys to lose , especially for a Hollywood movie . Now , if they had stuck with the books actual ending as people have discussed in the comments section , it would have been refreshing , it would have been different , but again , probably not a happily ever after type situation , but it would have been different .
