Like a few others have mentioned on here, the ending is such a disappointment. The book has brilliant twists but the movie is classic simple happy ending. Times are changing and I think people are getting tired of cliché happy endings. Imagine leaving the cinema if the movie ended as the book did. The thought provoking debate that would ensue between watchers would be great.
The love story between Langdon and Sinskey isn't needed.
I found Vayentha's acting poor. I couldn't buy into Sienna's role.Poor acting? Maybe.
I thought people should have died at the end of LOTR and that was over 10 years ago. Too many happy endings for my liking. This movie has betrayed the book to its detriment.
Not a happy camper at all.
