off the top of my head:
1) 2001 space oddysey
2) godfather
3) vertigo
4) nil by mouth (gary oldman)
5) bourne trilogy
6) wizard of oz
7) marnie (hitchcock)
8) alien (probably because i watched it last night)
9) deerhunter
10) apocalypse now
no accident that there's basically nothing in the last 40 years - a strong indication of how everything's turned to shit!
70s is what it's all about for me, though i have an open mind to anything before that
i absolutely couldn't stand shawshank redemption, or understand why anyone rated it. he seemed just totally up is own ass!
I don't know if you are aware but nostr has a reddit-type feature, 'communities'. it hasn't really taken off yet but there is one for movies:
(hopefully this works as a link)
