I felt it was a very odd chapter in some ways. The Lee and Gai comedy felt like wasted panels at this point in the story. Don't get me wrong I love those two but just not in this situation, they didn't contribute anything meaningful and whenever Tenten is shown you know it may as well be filler.
Personally I did really like Naruto not being able to absorb the other half of Kurama from Minato as I didn't really see that coming. I thought Naruto would get the chakra and then the reset button would be hit on the fight, only this time Madara is in super juiced Rikudou mode.
Lastly, (more of a petty gripe than anything) I said to myself "there isn't a chance in hell we find out who approached Sasuke" and much to my own frustration I was obviously right. I just feel that barely anything progressed and it was a "buying time" sort of chapter to further prolong this theme of Madara being untouchable. I love the villain winning, and I like seeing Naruto finally getting his after talking his way out of so many situations, but these past 5-7 chapters to me really feel hollow. It's like the manga tries to build towards something inch by inch and then falls off a cliff to start another new climb.
Anyway, I have no real theory as to who this man approached Sasuke might be, and I have no idea how Naruto will come back to life. Although, I can just as easily see someone reviving Naruto with a "very dangerous and risky jutsu" they didn't want to use for whatever reason. At this point I'm merely spouting off frustration though so I'll stop and wait for the next chapter to hopefully contain more intriguing contain than wasted panels on out of place comedy and a flashback we've seen already, there just isn't a need for that.
