My tolerance for old films is pretty low. Anything prior to the 70s generally looks and sounds bad to me, and even then, there's not that many films from the 70s that I like that much. It probably has to have Al Pacino in it for me to be interested. My grandad told me about how he saw The Exorcist in the cinema, and how people were screaming and crying in the theatre. It's baffling how anyone could have reacted to it like that, it's an inherently hilarious film, because it just looks so fecking terrible. I find it hard to believe it didn't look terrible in the 70s too.
I'm the opposite with music though. I find the roots of music fascinating, and how styles, sounds, musicianship and recording methods have all developed. Old delta blues sounds awful from a production perspective but that is crucial to its time and place in music history. Similarly the blueprint of heavy metal in the 60s and 70s, bands like Sabbath and Zeppelin sound rather tame in comparison to metal and rock from the 80s onwards, and they used a lot of goofy recording techniques back then too so some stuff sounds a bit weird, but it was all part of how music evolved. Hearing stuff about Link Wray stabbing holes in the cones in his amp cabinets to make them flap, creating a primitive distortion, I generally gravitate towards stuff like that.
Pre-20th Century literature can often be a bit of a chore to read too, due to how language has evolved since. I read Frankenstein recently, which is early 1800s. It was decent overall, I liked the story and the approach to it but I found myself having to re-read parts of it the writing style is so jarring comparative to modern lit.
