First of all if Lucas wanted to make another movie, he would. When has rejection or criticism ever stopped him? Hollywood rejected Red Tails so he financed it himself. Secondly, considering what he has done with the originals as well as the prequels I'm okay with there not being an Episode VII. Doesn't mean there absolutely won't be an another movie, just means that he won't be the one doing it. If he really cared what the "fan boys" thought he wouldn't have continued to make change after change in the face of such opposition, so I'm not buying it that critics are the reason for his decision.
