I rather thought the whole thing extremely disappointing. I love the book, for me the film was more annoying because they changed so many thing that just didn't need to be changed. I imagine hefty wedge from sponsors also meant the story was practically re written to maximise revenue.
For example, the ka in the film? A different colour to the book. Why? It's only a small detail ok, but then if so why change it?
Also instead of going to the library to do research, when he is on a bus he borrows a kid's phone and does an internet search on that. Interestingly enough, again a sony one.
I just think why change it? It was fine as it was!
And Langdon and Sophie didn't kiss at the end of the film, and I liked that in the book, instead there was this massively cheesy over americanised ending trowelled onto the audience. It was ridiculous. The film enRAB about ten minutes after it neeRAB to.
