Something I noticed that's becoming a pet peeve of mine is the "doomed anime mom" trope. She always, ALWAYS has those sad doe-like eyes, a braid, and maybe an apron on. And she always lasts only a few episodes before catching an incurable disease, or being maimed horribly, or doesn't survive to be included in the show at all and died in childbirth, or is always seen only in flashback.
I've ruled this out being sexism, because it happens a lot in series that show how badass women can be, particularly magical girl shows. And Disney pulls this shit a lot too, so it's not anything Japan-centric. It's just lazy, shitty writing.
