I think any movie that has “Jedi Rocks,” lousy outdated CGI splattered all over the screen for no reason, and a terrible edit of Greedo missing a shot at point blank is pretty much objectively inferior. IMO the only SE you could make a solid argument was actually an improvement is ESB. But even then, the differences are so slight with the Wampa and the Cloud City windows that it just doesn’t matter and there are still a couple things that bug me like the loss of the “Bring my shuttle” line. (Another example of a scene butchered by killing its pacing and emotional impact.) Of all the SE changes to the entire series, the only one that I think comes close to essential is making Ian McDiarmid the Emperor hologram in ESB. I’ve seen people nitpick about how it supposedly looks less like the ROTJ Emperor than the ROTS Emperor, but whatever, it still looks a helluva lot better than that other thing did and is a lot less jarring and continuity-breaking. My ideal cuts of the movies would probably be all the little clean-ups of things like matte lines, the Emperor hologram, and maybe little non-intrusive things like the Cloud City windows. And nothing else changed from the originals.
