They're fun if you like a game that demands skill building. It is trial and error at first, but once you develop mastery you start to learn how to apply what you've learned to different situations, and become able to do things like kill bosses in one try which feels extremely satisfying. It might just be you don't like that kind of gameplay and that's fine.

Like personally, I want to play a game that will punish me until I learn to approach it on its terms. I want that challenge. For me, I don't enjoy playing games that are too easy or not crunchy enough. I get bored too fast. I need that friction.

The real problem is the communities and they way they try to give this attitude that you should like this kind of game or you're inferior. They're insufferable. Stay away from them. Especially the reddits.

Also fromsoft really could stand to include some accessibility options. A lot of japanese game dev companies seem to have this "you play it our way because this is the game we designed" attitude still and it's... annoying.
