I haven't watched a lot of anime, but I want something with a sense of "wonder" that comes through worldbuilding, music and similar.
I watched and read Made in Abyss recently and it blew my mind. I loved it a lot, although I suppose there exists stuff that's even better than this.
I heard Naruto has really nice worldbuilding and stuff like that.
Anyways, yeah, anime with this feel. Maybe even manga as well, just something that can give me a sense of awe and wonder at its' environments and beauty. I even read a bit of the MiA anthology the author did and it just adds so much to my vision of how I see the world in Made in Abyss.
