One thing I will say is that I will never believe KOTCS was shot on film. It has that fake overly exposed look that early digital films had. It actually looks more fake than any of the Star Wars prequels.
In fact, I would argue that KOTCS was a worse film than the prequels. The prequels have great moments despite being flawed films and aren't really forgettable. KOTCS is very forgettable and doesn't have any truly memorable moments. The worst thing a film (or any work of art) can be is mediocre, and that word pretty much defined KOTCS.
The overblown, overlit hazy photography in KOTCS is truly one of the ugliest things I've ever seen in a movie. It makes the whole film looks like it was shot through a druggy haze.
