Ok, well if what I heard is true, I don't understand the problem about Sakura. In fact, this is a good thing for this chapter. I'll bet many would ignore this post, but feel free to do so, but if you're in need to understand her or just want to read for good support, then I thank you for your time.
Well, I don't know how is this Sakura's fault or anything bad around her. First of all, you should be happy that she's getting the screen time she's gotten and I know why, but let's go down the line. First of all, she got hurt from something, so she just got recovered from this. Here's the thing. Sakura just got Saving Private Ryan intro on. What I mean is that she got knocked, watch all of them getting killed left and right, then recover and the war continues. Simple as that. It's like getting hit a big blast and wake up realizing that one of your friend got killed/severely injured. You can't blame Sakura because of this. This is war and getting caught by the God Tree is like many going forward only to get shot by turrets. So now she got back up and wonder what's the current situation and heard Shikamaru got caught. Think as how Kakashi think everything is ok but then found out Obito got crushed by a boulder. So yes, Sakura can't be blamed. One moment that you can't resist the massive destruction.
Next, Sakura unable to help others. First of all, give her a break because at least she actually cares about everyone, which btw what a heroine truly is, not focusing on one or even yourself. At this point, you can see why Naruto and Sakura are the heroes, because they care about others. Does that mean others like Konoha 9 doesn't? Not really, but the reason why Kishi don't show that, whether true or not, is because that's not their place. They're side characters, not meant to have many dimensions to their characters. That's the main characters' job and if they don't have it, then the writer would need to write better in order to capture the audience attention. Also, the side characters, mainly K9, only get emotional when the classmates are the one to get axed, so that's the closest you get from them.So I really appreciate this chapter for showing Naruto and Sakura's agony because they're our heroes and stuff like this tells us this is their final mission. Not really because of Sasuke but in terms of terrorists' threats and all, this is it. But no, you want her to go all out asap when this chapter is about one final stand before everything becomes a waste.
So going back on not helping others, again, Katsuyu gave an reasonable explanation and again, Sakura was caught in the bad moment. When she recovered, everything was pretty much wiped out. While she can help one (Shikamaru), she wants to help all, because again, she's the heroine and that's what they do. But no, please kick ass. Look, I'm not saying she will or not, but calm down. This is a grief chapter, which by the way I called it again in the podcast that the next chapter is going to have talking and Naruto will end it with his ultimate determination. The funny thing is I even heard this talk and the guy even knows that medic equals very heroic, but again, since this is a Shounen, everyone must fight 24/7, but I digress. So yes, at least she cares about others, but unfortunately, Katsuyu minis are drained out, so to say, and pretty told her that they are in fact dead. Sakura was broken because they are dead and it's not that she couldn't save them because of her being weak, which is absurd. It's because a mass genocide just happened that happened to be done with a massive destruction that is the God Tree.
So now, we got some complaints about the emotional turmoil from her. Why is that a bad thing? She's going through what Naruto went and going through now. She cares about everyone, so of course she feels upset. Here's something you got to credit, at least she is worthy to be person in the Hokage's office for having that much care for her own people. She has grown up a lot but now, she's entering the hard process: losing thousands in a blink of an eye. That's why the RTN movie felt close to original characters because if people thinks Sakura only care about Konoha in that movie due to role switch, that's completely wrong. It's the fact that she really loves her home as much as Naruto. By the way, this is not a pairing argument, this is about Sakura, so don't go crying on me, I'm only going with the manga being told. This is why in that movie works really well because it will tell you that minus personality, her character would be the same. So needless to say, she is like Naruto in that sense.
That all being said of course she will feel pain. Naruto is, right? She felt the same back in Pain because her beloved home is gone at the time. That's why she got this kind of screen time and not so much on others because there's more to her and let's not forget one important aspect: she's made to be human. Heck, I like Naruto here because Sakura knows he's human, but not many others really don't get it. They have to look inside to understand that even though he's their savior, he's still human. This is why I like this chapter and sure, it's redundant for Naruto feeling this, but again, he's human and this is pretty much a setup for one final battle, in this war of course.
So should we be angry at Kishi for this chapter on Sakura? Of course not, but if you let the antis or even your own first impression, then you're missing the point. Who is to say Sakura is highly motivated after this chapter? Remember, in chapter 573, she don't want him to handle the burden alone anymore. Also, remember chapter 628, she was worried but after Naruto talked, she was very motivated to the point she said "Shannaro" which by the way means that she's very hyped. If you're a fan, you would know this already. The reason why she does so, without any pairing argument inserted here, is because she can relate to Naruto easily from experiences and characteristics. Why you think we got two panels of her reaction in 628? Anyway, the next chapter could very well lead to anything, but no doubt Sakura will get more focus after this chapter. Time will tell. Well I hope you have a good time reading this. It wasn't easy to be honest, because I held frustration on unnecessary, intentional or not, argument, so here it is, or at least partial of it. Anyway, don't get down. Next chapter, next volume, it should be a good one for her.
