Of course YA is popular on TikTok. It's primarily teens & young adults. The problem is publishers chasing that b/c they believe it's easy money. Marvel movies & remakes are the same thing. I don't like superhero movies, but it would be silly to say they're all bad just b/c Hollywood won't move on.

It's especially silly because YA is a genre that is often dismissed for not being intellectual enough or good enough and it also happens to be popular with young women, when the reality is that there are lots of genres with the "all very similar" thing, because that's how genres tend to work.
