Although I think Evirus should be commended on attempting an analysis, I don't feel the fire to agree or disagree and to quote at length. I watched 3 episodes of Bakuon and didn't care for the series. Omo found it worth the trouble to debate the point, so more power to him. Meanwhile, I'm more interested in Luluco, Flying Witch, and finishing YuuYuuYuu.
P.S. Really don't have the time to expound, but the pencil note for ep.03 was "it's barely watcheable, the manga is adapted very poorly" and "feels like a poor retelling". The key point is that the feeling of choppy story is not related to reading the manga previously. Don't read the manga poisoning into this.
P.P.S. Evirus is right that Hane is a more likeable kind of idiot. But I finished K-ON. Look at the viz.retrospective post to see why.
