I think you're judging the visual style as objectively, universally bad when the truth is that it is not to your tastes. I gather that you just can't stand it when things take a turn for the geometric. There's probably no point in pushing you to try it, then. No force on earth will make me like strawberries or bananas, and if I hear a chef has done something great with them, I still won't try it, but I also won't say that the chef's choice to put them on the menu was a colossal blunder before the whole culinary world. And I know there are perfectly good shows I don't intend to watch, either, and perfectly good books I don't intend to read.

Also, I want to make sure you understood my turn of phrase. The point is that making a part "better" by whatever measure sometimes does not make the whole better, even by the same measure. It's about, well, elements in harmony. The visual style goes with the writing and the setting and the humor. If you paired these up with animation that looked like the woodcuts of Albrecht Dürer, it would be technically impressive but the show as a whole would become garbage. If it were forced to resemble the style of 1980's Toei productions, the dissonance would be less severe but it would still be there.
