I give it a 5. I liked the chapter. An emotional chapter is needed occasionally. It's one of the reasons I enjoy this series. Madara stayed true to himself. Taking his failings with a grain of salt just like he did when parts of his plan didn't go as expected. No ranting, no raving, just it is as it is. Hashi and Madara got closure. Hashi always thought of Madara as his friend no matter what happened between them. Kakashi lost his power up, Obito did say it was temporary and they got their closure. After living 17 years not knowing his parents, Naruto got to see his dad in action and to let his mother know he's doing fine so they got closure.
It seems as though Tsunade will probably retire as hokage and hand the reigns over to Kakashi, which is probably why the sage played up Kakashi's role in sealing Kaguya. I also think the sage will discuss with Naruto and Sasuke what should be done with the tailed beasts before he leaves. We know Sasuke wants them destroyed because they were used as weapons and the temptation would be to use them again if they were left free. Naruto cares about them and would want them to be free. I think the sage will have to come up with a solution they can both accept because the sage cares about them too.
I don't see a final fight for Naruto and Sasuke even though I know many people will be disappointed if it does not happen. This manga is about righting the wrongs of the past and working together to make peace so I don't see how a fight between them fits into that. Because of their rivalry Naruto has always wanted to fight Sasuke to prove himself but I don't think he will feel the need to prove himself anymore. Unless there are rules and it's almost like a wrestling match just to test their strength, I don't see it happening.
My biggest disappointment is not hearing what Tobirama thought of the outcome. He was the most pragmatic of the previous Hokages and my favorite. While many people feel he was the cause of many of the problems that arose, I think Hiruzen shares just as much of the blame if not more for letting Danzo have so much power and do whatever he wanted to do. Everyone else got closure except for him.
I guess next week we will see everyone out of IT. I would think it was broken once Kaguya and BZ were defeated.
