In my own view, the people arguing that movies never available to the public in some archive-able format should be given secondary consideration kind of have a point. I've been to the Louvre. Several times. I've seen the Mona Lisa. So I can make my own judgement. But if someone in, say, 1525 said, "This is one of the greatest works of all time", and then locked it in a Vatican Vault for the next 500 years, I should be forgiven for being skeptical. (At least until 2025 when they brought it out from the vault. Whereupon I can make my own judgement.)
I'm not in the movie business at all, so I'm just a regular person, but I guess what I'm saying is, in 50 years, why do I have to just take the Academy's word that Film X is good? They'd be saying, "Trust us. We have a copy of it, and we've seen it. It's one of the best films ever." Which is fine. But why can't I get it and judge for myself? Why can't I get it show it to some friends and neighbors and talk about it? It's a legitimate issue in my view.
