Serious question: Have I been the only person reading this whose taste in art, film and literature for the most part actually has gotten more old-fashioned instead of more contemporary as I get older?

Keep in mind that I used to read very little fiction from before WW1 or so, and watch very few movies from before the 1970s... because that's where the biggest stylistic paradigm shifts so far happened in each medium. As a result, novels and films/TV series from before then often felt like an alien language for me. Maybe it's because I've acquired a more academic approach to art with a greater degree of historical consciousness, but I realized there's so many influential works I'm not familiar with so I've been doing a lot of catching up to do... so there might be quite a few cultural nods to influences in favourite novels and films I've never noticed. Another reason is that I've noticed that so many common approaches to avantgarde/deconstruction/transgressive art have become well-established traditions by now, so they might have maintained their potential to yield works that could be satisfying on an aesthetic level it remains debatable how radical they still are. (Expressionism, Dada, Surrealism etc)
