I think they try to put substance in bond's character, making him more human and vulnerable to emotional turmoil, which of coz.... will give us the "license to kill" off his perfection we thought he is all along.

Past bond films seldom showed he ever bothered by love problem, or let it jeopardise his mission. He's the alpha male and gets the girls, bed them and then gets away, continuing his mission. this time around, he actually got himself "lost", hold grudges and became unstable over women.

right on mate...
