Why do you find specifically Disney’s treatment of star wars so bad compared to before? We didn’t have the oot then either, so yes that’s bad but it’s not something Disney put in place. And I understand you don’t like the sequel trilogy and while I do I understand people not liking it but I don’t see how anybody could rationally say they aren’t better than the prequels. Even if they are less original than the prequels, they are way more competently made.
Rogue One being almost entirely reshot
That didn’t happen. Just normal reshoots and a rethinking about the ending.
Maybe you’re thinking of Solo?
I’ve heard that most of Solo was reshot, but a lot of Rogue One was reshot too, and I doubt just the ending and “normal reshoots”. Granted, we’ll never know because it’s classified information, but I suspect the cartoon Peter Cushing, the entire ending, the Darth Vader scene were added later along with most of the fan service.
