Star Wars has a lot of grain. and it is very soft, almost blurry in places. But it doesn’t have near the level of grain as say American Graffiti, i was watching a version that predates the blu ray without the dnr and the techniscope grain is like sand all over it. I can see managing the grain but they blu ray is awful detail is lost.
Would i watch THX 1138 and American Graffiti with all the grain intact, sure. But i’m sure someone would complain. George Lucas himself is the one who had Lowry remove the grain.
