I just watched these versions.
This is going to be controversial, but I think that you best get the feeling of the original movies by watching the pre-1993 movies. They were lifted directly off of finished prints, so the colors are right and there is grain where it should be. The sound and music and effects aren't mixed any differently unlike 1993. The picture is really, really sharp because the whole movie didn't undergo a smearing process (like 1993 versions).
I said pan-and-scan (obviously widescreen would be ideal) because the resolution of VHS/LD isn't great and you can actually watch the actor's performances and see this beautiful lighting and color up close.
The biggest difference I noticed besides the sound (which is actually mixed quite a bit different) is that there is a lot of contrast in the picture. There are shadows and areas of hard light. This "hard light", hard contrast look typical of movies back then was washed out of all of the newer versions, which look sanitized and wishy-washy.
To be fair, they do this with most remasterings of old movies too. But I love the sharp, high contrast, hard light look. And if you look at screenshots from theatrical prints of the originals, they will show you the same thing.
I don't know- I just got the feeling that I was watching the actual movie as it was, far stronger with these editions.
