I just don't like the model much. That's really the primary thing about an animated character.
Some of it's malicious and retarded, but some of it is intended to get her to improve. It's kind of a tightrope to disregard nonsense slung your direction while actually having the sense to pull up when the advice is good.
It's really a fairly common problem with modern animated series especially in the West when people can't seem to decide whether they want to do an episodic series where each episode is a self-contained thing, or have broad story arcs, relationship shit, etc., so you end up with these confused series that sometimes follow an arc and sometimes just drop stuff on the floor when they roll the credits.
