Same here, though my suspicion is that this solely due to the fact that I was a Teenager back then. There is a Name for this kind of phenomenon that people will usually like the things the most they discovered at around ~14..
I'm partial to the 1960s. David Lean did Lawrence of Arabia and Doctor Zhivago. Kubrick had Dr Strangelove and 2001. Hitchcock put out Psycho, Kurosawa did Yojimbo. Cool Hand Luke, Sergio Leone's Dollars Trilogy.
Cinema was really ambitious and huge in scope, and directors with an eye for photography were doing some incredible, slow, lingering shots.
As much as I love modern films, I love the 90s most of all. Action films, especially. Films from that time seem cheesy and dated now. At the time they weren't cliché, they were cutting edge and building the cliché.
