(i was gonna ask this in the mary sue thread but i think this extends beyond mary sues)

who do you think is a good female character?
what would you like to see in a female character that makes her well written?
what should writers avoid when writing female characters?

i ask, because there seems to be a lot of autistic slapfights debates (be it sjw harpies or comicbook neckbeards) about what makes a female character 'good'.
