I actually enjoyed the chapter. The black ink is getting annoying though. Its like Kubo just spills ink all over the page. Half the time I have no clue whats going on. Aizen definitely made this chapter epic. He has become somewhat interesting again.
Still reminds me too much of Naraku from Inuyasha. Hopefully he doesn't lose and keep coming back over the course of the manga. Having only one villain is rarely good. Hopefully his arrogance is completely and undeniably warranted. Thankfully it is so far or should I be thankful. I fear Kubo will take the other route and make Aizen so freaking powerful that every single character in the Bleach Universe will need to jump him and still lose. :(
