Honestly I'm still trying to recover from the massive mood whiplash. The absolute last thing I expected coming into this chapter was an extended comedy routine with Team Guy, I understand the need to have some levity in the story to balance out the darkness but to me it just felt out of place, or at the very least it went on a little too long.
I would be happy to see more of Tenten but it's definitely too little too late, she's barely been a character for so long that her showing up now doesn't do much, though wouldn't it be the absolute pinnacle of irony if Tenten was somehow involved in the defeat/sealing of Madara.
I do agree that Madara spitting out and dismissing the Sage's ninja tools is Kishi spelling out his way to beat Madara in bright neon letters and possibly a way to revive Naruto if the Kyubi chakra possessed by Kinkaku and Ginkaku can be used. I fully expected the situation with Naruto to go from bad to worse this chapter so Minato failing didn't shock me, but his flashback with Kushina was enough to make me enjoy the chapter and I wish we could see more of them more often.
It's funny coming into this chapter how certain it was felt that the mysterious man was Kabuto and now it's not quite as certain, why would Karin not recognize him and I doubt his ascension to a Sage changed his chakra much at all but I wonder what was the point of teasing the mysterious man last chapter if it wasn't payed off this chapter and we're left wondering a while longer.
