*Sigh* Ok, I"ll clarify. My mistake, when I said 'filler chapter' I meant more like Kubo used this chapter to pad out time than to really advance the story in a meaningful way. I'm aware of the definition, i.e. episodes 317-342 are a 'filler' arc.
Two page setting spread was pretty freakin' sweet, I have to admit. Want moar of those. (Although the slicing of the guy's arm was presented as REALLY random, I mean come on).
Reading it again now that I'm not extremely fatigued (which was a mistake), I feel it wasn't that bad, but not great either. Just okay. Hence, my 3/5. Come on guys, I'm one of the staunchest defenders of this series. No worries, I'm excited too.
