I’m not a strict purist, so I don’t mind the idea of older films being tweaked or visually polished in small ways, but most of the SE changes are distracting and actively detrimental to the films, for no good reason. The added effects have aged poorly, for the most part, and are poorly integrated into the films. Not to mention, I resent the fact that they’ve been presented as the only, “true” versions of the films rather than just alternate variations.
I’m content with fan preservations from now on, for sure.
