Ummm . . . . how do you make a fan-edit resto of a movie in 4K when it has never been commercially released in anything near that resolution?
By 2020's, the 1997 SE changes will be 20+ years old. There was only 20 years between 1977-97 the first time.
My point is that the SE's really won't be a "recent" set of changes anymore and I think this will work in our favor in terms of their legitimacy. This will be like a movie coming out in 1957 and then it got some controversial changes made in 1977 but they are now looking dated & creatively questionable.
As long as I'm on a general rant about OOT restos, we fans need to get more vocal about the garbage mattes issue. This one bothers me a lot more than a couple seconds of uncolored lightsaber or the wrong ILM model of the Falcon in ANH.
That stuff may be "original" but it wasn't visible in the movie theater like it is on home video. If it was, ILM would have taken more steps to reduce it originally.
It has basically turned into an alteration of the movie just like fading film stocks or degrading audio tapes. The issue will probably keep worsening with each improvement of the image quality until corrective action is taken.
