I grew up on the Roger Moore version of Bond, but between him and Timothy Dalton (I liked The Living Daylights), Bond was getting too cheesy with special effects.
I enjoyed Pierce Brosnan's version quite a bit.
I had never read the books until about two years ago.
Bond is a dark, gritty person. In the books, when I read scenes with him interacting with quick wit, or with the women, Sean Connery is who I picture, but when it's violence to get the job done, I picture Craig. Craig's dark and violent Bond actually fits the books better than just about any other Bond, save the original, and even then, Connery wasn't cold and brutal enough, even though for everything else, he fit perfectly.
Brosnan and Connery had good humor or could deliver a witty retort or puch line. Dalton and Craig more ruthless IMO, maybe closer to the books.
However, since Fleming preferred Niven he muse have liked some wit and a twinkle in the eye. Very suave.
