thoughts about yanderes?

what do you think makes a yandere well written vs what makes one poorly written in all kinds of media?

do you like the yandere trope or do you think it's overdone? and do you think that the way it's done right now doesn't do it justice compared to let's say older animes such as higurashi: when they cry?

drop da opinions and thoughts (▰˘◡˘▰) i'm curious to see what mangago thinks of the yandere trope considering there seems to be a split of loving it and hating it lololol
