The concept of the movie was sound. I just didn't much like Lazenby. *shrugs*
Moore wasn't bad. Obviously a funnier/goofier Bond. I thought he did a good job of it despite that. Fun movies to watch if not exactly like Bond.
Dalton was quite a bit more gritty. He was more like the books, in my mind. I liked that.
Brosnan was a nice between-Bond. Little like Moore in the humour, little like Dalton in the grit.
Craig I like a lot for the same reason I liked Dalton. He certainly has the realism and grit. I do miss Q and the gadgets, though, even though they're not so true to the books. I know he has some more believable gadgets like smartphones and whatnot, but it's not the same as a watch laser or briefcase plane or submarine Lotus.
Connery will always be the best, though. =P
