Dalton and Craig are two different Bonds
"Dalton was the original realistic Bond. Craig is just a clone"
"Craig did exactly what Dalton did, except way better"
I truly hate these comments because their portrayals of the character were very different. Yes, it's true both have a darker portrayal of the character but just because both Bonds are violent doesn't mean one supercedes the other. Moore and Connery were both Bonds with charm and humor, but I wouldn't that Connery was obsolete or that Moore was a clone.
Their characters have a number of differences.
Dalton was a tall, dark and handsome ; Craig was short, thuggish, blonde and sexy in his own way.
Dalton was more prudish ; Craig was more of a lustbomb, eager to show off his great body.
Dalton was able to portray the character with a lightness and somewhat of an enjoyment of recreation ; Craig's character had a certain bloodlust about him which wouldn't let him enjoy anything.
Dalton was more energetic, theatrical and expressive ; Craig was more stoic and hardened.
Dalton was able to take a woman out to a carnival and carry a big teddy bear ; Craig's character was more rugged and masculine.
