The main problem IMHO is it's become formulaic for Demon Slayer. They have a bit of a fight, then right at the end they are like "here's the whole back story to make you feel something". It feels a little forced and corny. Why do I need to know and care about every bad guy and their back story? Sure, it adds emotional weight to the moment, but it feels very forced and, like I said, formulaic. But I mean...Demon Slayer has been on that tip its whole run, so I don't see why it would all of a sudden bug people now
