Eh, this week's chapter was alright. Not bad, but not good compared to chapter 657. There was hardly any story progression except for the very end, so it felt a bit like filler imo.
Nonetheless, it was quite cool to see Gaara in the spotlight, along with the Bijuu smacking around Madara. Serves him right for being overconfident, but I expect he'll have his brutal revenge next chapter.
I can understand how he managed to survive being smacked around and losing an arm (along with an impromptu eye transplant), since we're aware that part of Hashirama's power was healing without the use of seals/medical ninjutsu. Plus, we've seen Tsunade decapitated but still alive, which is arguably much worse than Madara's condition.
However, the thing I don't understand is how Madara escaped the binding with Susano'o. I guess it makes sense if one can use Susano'o after unlocking it even without eyes, since it's basically just a manifestation of chakra at that point, but it's usage should really be limited to those with the Sharingan activated. If Madara had Susano'o all this time, why didn't he activate it to fight the Bijuu? Seems a bit weak on Kishi's part.
Overall, I gave it a 3/5. Great action and all, but Madara's part could have been done much better and with more creativity.
