I really liked this chapter. The last page is completely ridiculous, it was just awesome. I like that when we learn more about characters and their interactions they are drawn from new angles, like it was with Nemu and now with Yachiru. So I think now we will learn more about Kenpachi, Yachiru and Hitsugaya. At last Hitsugaya will have some development, he was becoming way too static and useless.
Also I don't understand why so many people disliked this chapter. If you look from the point of view of "asspulls", you'll be disappointed, because they are everywhere, not only in shounen, not only in manga, but also in almost all other works of fiction. Any plot twist or plot device can be considered an "asspull". But it doesn't mean that it can't be enjoyable to read.
