Do you honestly think we should base characterization on the things they did in the 80s? O.o Or that no "classic" tropes are ever wrong? This is tv, intent doesn't matter, content does, and when you make someone with a possible disability the continual butt of jokes, that's wrong. I've only seen a handful of episodes, but that's how it came off to me. They could have also done a touching episode where she saves the day despite personal challenges and whatnot, then treated her with more sensitivity, but this is what they decided on.
