-- Nobody agreeing on a "best" version of ANH :
I think it would be very simple to please the vast majority with one hybrid version of the OT now : Technical improvements in, creative changes out.
IMO this one-sentence editing plan would pretty much bullseye what the public really wants with very few exceptions. Or for that matter, do some surveying work and you could probably come up with an even more detailed list of things people do and don't want. I think the public's feelings on what they want out & in are probably pretty consistent overall (diehards notwithstanding).
Unfortunately this just makes way too much sense for it to happen. Even as well as Disney is trying to handle SW, I'm not optimistic that such a straightforward sensible thing will get done. We are probably facing a future of our ideal version of the OT being forever split between an original cut with distractingly dated SFX and a SE with frustrating creative changes.
Well, a few things.
1. "The public" is largely apathetic as to which version of Star Wars they watch. The longtime fans probably want ALL of the versions, if you poll all of them. That means SEs, and theatrical versions.
2. "Technical improvements" is a broad concept. Arguably, it's a "technical improvement" to crush the blacks or screw with the color timing in ESB. It's a "technical improvement" to make the sabres look like they do in the prequels as opposed to the theatrical versions. It's a "technical improvement" to colorize a black and white film, Mr. Turner.
-- "The original versions are perfect, just canonize them and forget about it!!!"
Yeah, we're sick of Han shooting first. But don't tell me it doesn't help the movie to have the SE redone battle of Yavin.
Younger generations won't love the 1977 sfx. Deal. Its not our duty to hurt their enjoyment of SW just to try to make them appreciate how far things have come. Technically improving the sfx is not different in principle than cleaning the 35mm print or fixing the soundtrack when you get right down to it. And besides GL, nobody is calling for wiping away the existence (or even widespread availability) of original versions.
Here's the thing: I don't care. The same way that it's not the job of the older generations to HARM the enjoyment of younger generations, it's also not their job to IMPROVE their enjoyment. It doesn't really matter what younger generations think about the films. That misses the point entirely.
The point, in my opinion, is film preservation. The films should exist in versions that preserves what people saw in 1977, 1980, and 1983, respectively, when they went to the theaters. The goal is no who will love the newer versions more or less. The goal is to let the films be taken at face value, on their merits, for what they were at the time. You want to clean up the image by removing things like dirt from the negative? No problem! That's just preservation. But even when it comes to things like the matte boxes for the Tie Fighters and such, I say go ahead and leave 'em in.
Now, I should clarify, I'm not saying that the SEs or some "living version" of the OT can't be done
in addition to this. And, at least from my point of view, I can see an argument for
minor technical improvements (as opposed to image preservation) like removing matte boxes or otherwise "cleaning up" various f/x shots. But for purposes of film preservation, I'd prefer all that to be kept to a minimum. No new digital backgrounds -- keep the old matte paintings. No new sabre f/x -- keep the old stuff. No new gobs of ships in the Battle of Yavin -- keep the original number. No new cantina denizens -- keep the old ones, wolfman masks and all.
Star Wars was a thing that happened at a particular point in time, and was a staggering achievement in its historical context. You want to restore the image? Go ahead. You want to
improve the image? Save it for the "Special Editions" or "ongoing editions" or whatever. But keep an archival copy of the films as they were on release. We can debate which sound mix is the "definitive" mix, but other than that, preservation only for whatever archival version.
As for canon...I give not a fig for what people tell me is canon. I make my own canon.
