The irony with Lucas is he has become the very evil he originally fought... He took on the massive studios with creative genius and new ideas and hated the film establishment. He is arguably now more apart of that establishment than anyone from previous generations which has meant that...
I think Lucas has become utterly detached from his fanbase, and I think the split from Kurtz back before RotJ showed that then Lucas had sold his soul even back then. Ever since he has seen Star Wars as a means of selling toys and making money rather than about being about film. I think the latest Indy film, with aliens in, showed just how detached he has come from the fans of his films..
In the prequels he then seemed to think that special effects exists to drive story, rather than story to drive special effects. With that in mind is it surprising he adds duggs to the OT rather than run colour correction?
This is no disrespect meant to either Harmy or Adywan, but the fact that one individual in either case with great editing skills and a lot of perseverance and patience has managed to do a better job on fixing (and editing) the issues in the OT, than all of Lucas Film put together shows just how far the company has fallen, from the par excellence and creativity that they once represented.
I will just leave this in here for now.... http://www.youtube.com/watch?v=1zwID2QHnV8&feature=related
