The younger fans haven't watched the media you're referring to, so they have no reference for what has been done before and better. For them, this is a first.
The older ones are either womanchildren who tick all the usual boxes when it comes to what they seek in media: hot guys (nevermind they themselves being ugly and sometimes fat), hot women acting like dumb kids (they say that "woman don't have to be perfect and can finally act like little gremlins!", nevermind the bajillion times it has been done before) and of course a "female empowerment" message.
Manchildren like it because they masturbate to the girls, that's it.

Being on Netflix meant that a lot of kids and a lot of adult-children had access to it at the height of the kpop craze, basically being at the right place at the right time.
