i think miraculous ladybug should be legend of korra season 1. in the sense there's like a romance plotline that drives a lot of character drama but the main driver of conflict is the setting itself of a nitty gritty under city with a lot of problems with a heroine slowly discovering it outside of its sparkly exterior - mostly set at night, noir type aesthetics and undercover missions, an intimidating faceless villain that manipulates crowds. the thing is that legend of korra also sucks to me but more in the political messaging it does (it doesn't let korra make any substantial changes to her world) but it's a shit ton better than miraculous ladybug. but generally i think lok season 1 is the Vibe and Tone that the miraculous with the current themes would most fit? like aiming for an older audience but not an ADULT show.
