There is nothing wrong with changing your movie, and playing around with "what could have been." What is not okay is when you completely neglect the original film, the film that made it what it is. Even if the new cut is better than the original, it is wrong to simply cast out the original, which is exacly what Lucas is doing. Yes, he is releasing the originals, but it seems to more like Lucasfilm did, and Lucas just begrudgingly gave permission (as his quotes suggest). I have very little respect for a man who doesn't respect his own work.
