It's not just the 60s. There are STILL people exactly like I've described running around today (the hard-smoking, hard-drinking, womanizing, ruthless killers for hire...well I haven't met any killers for hire)
But at least THAT's a character. Broccoli and Wilson have been so busy since the Dalton days to remove everything about Bond that made him a character, we see whoever it is that Daniel Craig is supposed to be playing and even HE doesn't know. Why do YOU think he's been so eager to leave the franchise for at least 2 of the last installments?
The current Bond has no personality whatsoever, he's almost a robot.
