I hope there isn't a Craig backlash. Things will really have to go downhill for him to have that happen. He truly reinvented the role of Bond with even more pressure on him. I feel for whoever has to follow him. I will be sad to see him go, but don't want him to overstay either and I'll be rooting for the successor as I am a Bond fan first and foremost.
The only other actor I was sad to see go was Dalton because there was unfinished business there. It didn't mean I wished to see Brosnan fail as I wanted to see the series continue. At the same time I never bought into the hype thrust on him, the best Bond since Connery and billion dollar Bond and all that. Thus any sort of diminished returns from the Brosnan era given Craig's unique interpretation is understandable
