And yes, file this one under “can’t unsee”. Haha, that’s about my only problem with the hands-on aspect of us all having to make up for what Lucasfilm won’t give us, we keep stripping away the magic more and more all on our own by having to over-analyze/scrutinize these classics. Hell, there’s probably been more work put into saving/preserving/reconstructing these films than the man-hours that actually went into the original meticulous creation of them (case in point… these marks).
