The arcs have been pretty much all about Batman in this season/what I assume are the later novels, which I think is fine. As an interesting character study, I think it fulfills the promise of being a "friendlier" or more palatable version of Aku no Hana or Watamote, where it's a self-hating protagonist who learns to connect with some aspect of the society that he despises.
For me, I find it to be a less subtle version of the Hyouka/Oreki arc - down to the fact that, as I suppose Shirobako has shown, the animators went to the trouble of deciding how to animate Batman's crying-anguish face. That's not a bad thing, but that's just what it is.
