As long as it is a faithful restoration and the negative grain, Not dupe grain is intact and we get the original audio and colors. I don’t see an issue.
I haven’t liked the audio samples for the new mix. I like the 35mm Stereo. I have never heard the 70mm mix as it has never been available. The Mono Mix is great for what it is.
It will be weird to hear another mix for Star Wars, just how many mixes now can we count. The first film has had an insane amount of revisionism through the years. Just for the mix in English. I haven’t kept track of the foreign language dubs, I’m sure that gets interesting too.
