The recomposited miniature effects are an unambiguous improvement. A tasteful, subtle enhancement that gives the original visuals an entirely new level of realism. If Lucas had stopped there, very few people would give a crap about getting their hands on the theatrical versions.
I really hate this change. Linguistics is a hobby of mine, and Aurebesh is one of the most poorly designed fictional writing systems ever, if not the most poorly designed one. It’s really just the English alphabet, with a few digraphs given their own letter, but the digraph letters are optional, anyway. I’d rather not think about it. I’d honestly prefer changing all the Aurebesh in the movies to the Latin Alphabet over changing that one piece of Latin to Aurebesh. I hate Aurebesh.
Aurebesh wasn’t created to be a plausible alphabet or even to be readable; it was created to look cool in the background of a movie in 1983. It’s more than adequate to the purposes of the original trilogy. If you’re watching those movies and all you can think of is “lore” and “worldbuilding” piled on years later, you might be watching them wrong.
