Yeah, well, he's been upfront about changing it, he's even giving out samples. He's allowed to follow through with his word and do what he wants with his own material, he does own all the rights...
If TTG set out to do that for some strange reason they would be entitled to do it, it wouldn't be behind anyone's back or dishonest or wrong if they were upfront about it. But, it would be very strange.
Lucas means well and forgive me for my sins, I do believe Star Wars has aged very well, better than some 90s films XD but I happen to like some of the special edition changes.
OMG, I said it...I said it...oh no! OH NO!
With all due respect to the original, I still like some of the later video re-release touch ups.
I don't see why I shouldn't, it's sort of strange to get that attached to the originals that I hate touch ups that add to the story, narrative but we're a sentimental species.
