I’ve heard there’s a trope called “Seinfeld’s not funny.” It’s named after the idea that a lot of people who watch Seinfeld today think its jokes are overdone or cliche, not realizing that the reason they’re overdone now is because they were popularized by the show.

More generally, it refers to works that are seen as cliche nowadays by people who didn’t grow up with them, but were actually the ones to start the trend in the first place, when it was new and innovative.
