I like the movies, especially Ultimatum.

Right now I'm re-reading the books. I'm in the middle of Supremacy. It's amazing how different they are. I'd recommend picking up the books if you're into spy thriller stuff. The characters of much more complicated in the books and their backgrounds are in some cases entirely different. Enough stuff happens in the first book to fill the whole trilogy of movies. Still, the movies hold the spirit of the books remarkably well.

I'd definitely recommend the novels. Given the Bourne Identity was written 1975, it's really cool how well it holds up given how the world has changed: the cold war was still hot, America just got out of Vietnam, there were no cell phones and no internet. Still the book does not feel dated.

When your King calls you to action, will you hear the call?
