What anime should I watch if I want to be thinking for weeks about how good it is?

I've seen aot, demon Slayer, one punch man, death note, jjk, mha and Vinland saga. I really want to watch another show that has really deep themes and keeps you thinking. So something like death note and Vinland saga in that aspect. I want something that really makes you obsess over like Ben 10's watch and you just think like what if I had that. But yeah please help me I don't know that to watch. 🙏🙏🙏🙏
