Bourne movies were better to me than the books. The books were good but a lot more confusing. They throw out a lot of names and to be honest I found myself having to go back a lot to reference those names. Anyway, in instances you have a book that's better than the movie, I think it would be hard to make it as good. If you think about it, if you have a million people read a book, you're going to have a million different ideas of what the characters look like and the setting look like. Then you have a shorter time frame and the filmmaker having his own idea of what the movie should looks like.
