Quality is nice, but I don't think it is all that necessary to enjoy a film. What it takes to enjoy it is appreciation of what it is, where it came from, and for who it was written. That is why I could enjoy 2001: A Space Oddysee just as well on a shiny new DVD as I could on an old VHS (if it is all I could get my hands on). That fact that my old Star Wars pan and scan VHS tapes look almost as good as the only DVD release they have gotten is pretty shameful though.
EDIT: And man are we off topic.
