So since the manga's called "I like you" I'll guess I'll start with my opinion on that. Kakashi's sudden optimism is kind of, I dunno, forced and silly. Team 7 isn't acting as a team because they care about each other, but rather because as it worked out it requires two out of three in order to seal her (with no other option) and Sakura there to make it easier. It really does remind me of the bell test, where there are only two that can possibly get it... but in order for anyone to get them at all, all three must work together to take down the difficult opponent. I consider that this set up would have been the solution to Kakashi's bell test in Part 1; granted, with less theatrics and god-scale jutsu hehe. Yet, working as a team is one thing, but being likeable is another. I assumed Kakashi didn't like them because a) he didn't know them and b) they don't have any impressive bonds with each other like what he had.
Naruto and Sakura he understandably likes, and they deserve his affection. Sasuke on the other hand mere chapters ago had verbally smacked them down, cast them aside, and would have let them die if he could. Sure, maybe now he sees 'use' in their being alive, but only for the purpose of his goal. Overall, he has the mentality more reminiscent of a younger Kakashi--the so called "scum" that Obito had named. Why would Kakashi like him? I suppose that's really the question you can ask anyone who feels anything for Sasuke lately. I think Sasuke's special affinity is the ability to get people to like him even if he does everything in his power to make them not like him. No wait, that'd be too much effort. He just doesn't care.
Now onto Sakura! It's not one of her most impressive feats, but I like that she's included at least. I take what I can get, not even gunna lie, but she's still the number one stunner of this arc so whatever. It's a simple move with a purpose. She swoops in from the top, because perhaps Kaguya hasn't factored in that Sakura would be able to step in and do anything, so when she began to rise she didn't anticipate the attack from above. Sakura may have been calling her out on this mistake. From one woman to another isn't the worst mid-battle cry I've ever heard... Naruto's coolest guy still takes the cake but it is a bit of a heavy handed statement.
It's also unfortunate he calls attention that they're both women when they're obviously handed the short end of the stick. Kaguya is probably the most ineffectual villain with the least personality and the most lacking motivation in a manga where other (all male) villains take arcs to explain their side of the story. It super irks me that Kishi didn't let Kaguya speak and strategize for herself; Black Zetsu needs to exposit and make suggestions to her from the little sleeve, as if a goddess can't take authority on her own. At least this in a way makes her the least painful of the villains, because she hasn't reached that point where inevitably all villains in this manga reaches for me. Zetsu on the other hand... ugh. Get him away.
