Yeah, I think there was plenty of stuff to still explore, and he seems to be doing that rather than just creating something totally new. I mean, if the manga had ended and we never knew why Chad had some special power even though he was human, it wouldn't be the end of the world, but having these new people be the same sort of humans as Chad and exploring his power more is a good way to go. I hope we'll be learning more about Isshin, too, and why he left Soul Society and all that.
