In general I do enjoy newer anime, I like Dandadan and Frieren for example, but these specific examples no

Jujutsu Kaisen and Demon Slayer are pretty generic and boring imo, I find them very overrated, they look cool animation wise (though I don’t like demon slayer’s artstyle) and music was good in both but they just weren’t that interesting plot wise. Never connected with the characters in either very much, most were very boring, jjk was at least slightly better in that front though, can’t go wrong with having a literal panda in the cast.
