I recall it was thought to be a bit too filtered/denoised by some... as usually happened w/ films of that era, especially from Universal back then in the earlier days of BD (nearly 10 years ago). But truth is these flicks, especially the first one, just won't look very sharp (at least by modern, hirez digital standards) at least in part due to all the optical effects... and I really gotta wonder if 4K will reveal anymore detail/quality over BD for them. I suspect not much, if any... though the 4K digital streams should probably be noticeably better than the current HD ones...What was wrong with the original Blu-ray release? I have the 25th Anniversary Edition from 2010, which was the last time I purchased these.
I remember the misframing on the original DVD release of Part II and III, but nothing about an error with the original Blu-rays.
I am not equipped for 4K. Is there any reason for me to double dip for the new edition? I skipped the 30th anniversary version from 2015.
BUT... as I said, I'd love to be wrong on that...
