Movies? For the most part I plead ignorance, but when Casablanca was shown on our national tv, the movie critic of the local newspaper gave it a rating of 6 stars (on a scale from zero to five). I agree. So did my Slovenian housemate in the 80s.
Rio Bravo is the western that would be on my list. Hell, if I can stomach and even enjoy John Wayne's mannerism, then the movie has to be pretty darn good. Some Hitchcock films would also make it to my list.
It does sound like my taste is close to that of the Emperor. Glad you brought up Kurosawa. The movie fanatics in my high school class would have probably given the nod to Dersu Uzala instead of Seven Samurai, though. And when watching Citizen Kane I was expecting a larger than life experience, and can't help saying that I was a bit disappointed.
Also it is kinda pointless to compare movies produced in different eras. The changes in technology act as divides. The first movie ever was mostly a feat of engineering. Similarly, when sound, color, <missing steps here>, computer animation,... were added to the technical repertoire, it took (will take) a while before the great artists master them. Same thing happens in the history of music. We shall never know what kind of pieces Bach or Mozart would have composed for piano, or ... electric guitar.
