It's funny, because GL's decisions regarding the special editions and prequels has not only made me question his current connection to the Star Wars universe, but it's forced me to reconsider how much of the OT's success can truly be attributed to him and him alone. The prequels are pretty clearly a testament to what kind of product George will produce when he surrounds himself with yes men and the ideas are 100% his.
If it weren't for his contributions over the past 15 years, I never would have doubted that the OT was 99% his vision. But now I do. That's irony.
