I agree with this.
Changing your art and storytelling
style is completely different, unless you mean you go back and make newly updated re-releases of your work. But even then, you're perfectly entitled to that. Every creator is perfectly entitled to reinvent, remake and re-edit his works however he or she sees fit.
However, the fact that George Lucas feels the need to do this over and over strikes me as being indicative of larger psychological problems. It's like he won't get over the franchise AT ALL. Keep in mind that he has been tweaking these movies for over two decades now.
I think this whole "going back to fix things" fetish of his becomes a larger source of upset simply because there's this consumer mentality of 'keeping up' that has become bigger and bigger in the age of collector's item director's cut extended edition video releases.
Surely, no one's going to mind if I decide to rewrite articles constantly in the privacy of my hard drive. And surely, no one makes a big deal if a book gets five 'revised' editions published in the span of twenty years.
But film fan culture --- especially for fans who subscribe to the '
auteur theory' of film --- is built entirely around wanting to own the 'best' version or the 'definitive' version of the films. It's a commodity fetish that will never be fulfilled so long as Lucas chooses to keep redoing these films.
I don't think you can compare it to other forms of perfectionism or artistic prerogative. So long as his tweaks are put out in commercial video release then the line between personal satisfaction and commercial ethic remains fuzzy, and that makes tinkering with them a far cry from modifying your car engine for personal satisfaction.
It's also not the same as 'reinventing your personal style'. That would imply that he's trying to retell the story. It's not the same as a 'revised edition' of a book that incorporates footnotes to explain antiquated cultural references, or add new discoveries related to the book's topic.
What he's doing is very simple.
He basically said, "I was never happy with those movies. So I'm gonna fix it to make myself happier, and then you can all buy it and I can share the new more satisfying version with you all. And we'll all be happy?"
And then he said, "From now on, you will never be able to see the original version again. Last chance to buy it. We'll all be satisfied with the new version anyway, so what's the point of keeping that around?"
And then he said, "Hey you know what? Still not totally satisfied."
