Well, as I've said before, I like Yurin's character design. I guess the older folks suffer a bit more from the designs, but it's not really that bad. The most important thing is that it fits the atmosphere which it does.
People judging the designs in a vaccum are obviously gonna fail, and I haven't seen any argument against it which doesn't boil down to severe tunnel vision.
Case in point, nobody has used any negative rational opinion yet; it's all blustering about idealized Gundam series and other generic appeal to emotion, or some kind of abstract elitism, aka nonsense.
