What is it about pre-1960s movies that makes me hate them?

I don't understand. Something about them just bugs me. It's not the black and white. It's just like, I can't relate to them at all or something. I don't know what it is.

Some movies I love, like 12 Angry Men, Paths of Glory, Freaks, some Hitchcock movies, etc. but that is because those movies were way ahead of their time and are entertaining in the same way modern movies are.

I've tried to watch all the so-called classics like Casablanca, Citizen Kane and all that shit, but I just cannot get myself to like them at all.
