Also, the lack of grain is actually the thing everyone should’ve done with the Star Wars prequels as they were shot digitally (at least for AOTC and ROTS, TPM should’ve had the grain).
I assume you’re kidding? If you’re going to go down that path then the resolution should be 1280×1024 since that’s what you saw in a digital cinema in 2002 or 2005. Most people, like I did, saw the movies on 35mm in higher quality.
