Is it really a closure?
I'll be honest I don't care about Hinata anymore. I used to like her, then I hated her, now I am completely indifferent about her. I don't know if this is my fault or Kishi's fault. I would like to think it is Kishi's fault for not doing anything with her except the obvious for so long. I just didn't care. Unlike Sakura who we saw go through trials or even other side-characters like Shikamaru who went through his sensei dying, but Hinata....it seemed like her only real problem was not being with Naruto. Granted, she has other problems in her life, but the manga made it out to be like it was no big deal. "Her father hated her and said she wasn't strong." So? She was still going to be clan leader regardless and it just seemed like "It's not important enough to touch upon." The manga itself ignored it and ignored it to the point that even we forgot about it while reading. Just like Hinata, it was a background problem that didn't really matter.
Now, we have these moments of Hinata now and you yourself say this is closure for Hinata. Okay, what closure? Her being a leader of her clan? Her being a stronger person? The manga never cared about this before so why now? The only issue the manga seemed to cared about was NaruHina. That seems like a bigger closure than her being a leader to her clan so why not just close the pairing out? Yet this is one topic that seems the most important that Kishi continues to dance around. Like I said, ask a NaruHina fan and I bet you the most important thing about Hinata is not her strength or leadership to the clan, but her love for Naruto.
I just don't care anymore and I realize that this is really sad. Some people hate the Hinata panels, others like the Hinata's panels, but I...don't care at all. I seriously just don't care one bit about her character or whether or not she becomes a clan leader. I don't care if she gets stronger or if she lives or dies. The NaruHina fans and Hinata fans try to persuade me that Hinata is more important than I think she is, the manga itself tells me otherwise. Kishi...I don't even think Kishi cares anymore about Hinata. I think he is just putting her there just to do it. It would explain a lot. Unlike other characters like Sakura; like Shikamaru who at least were good enough to show these progressions. To see them face trails and continue to either fail or prevail shows that he has a thinking process for them. Hinata though: "There is a problem, then it is fixed." You don't see Hinata struggle with the problem. You don't see her standing up for herself against her father. Heck, she barely did against Neji and it was Naruto who ended up changing Neji's mind. So again, she left it to others to solve her problems for her.
I really want to ask now...why should I care about Hinata now? If someone can tell me a good reason, then I will change my beat, but now I don't even see Hinata anymore unless she is forcibly pushed into my face.
Hm, perhaps a bit of both. People really fixated that her plot is Naruto, and while Naruto is needed for her development, it's not that he's the target to do all this, rather a source of it. In fillers, manga, anime, or even games, it's about Naruto giving her a seal of approval if she is strong or not. I believe she asked this before she went unconscious in the Chuunin exam. She got her answer in this arc. Pain Arc was like a buildup and asking for one more chance to see if she is strong and I guess you can say it takes a near lost situation to push her. Now, in this battle, it's about showing them their result of these past developments, which she has shown as well as others. Is it closure? Yes and no (maybe). Yes, because there's no more room to add to it since she finally achieved it. No, because perhaps when the war is over, she may get a few words from her father about the loss of Neji (if he doesn't get revived) and the future of Hyuuga (her being ready). That is if her father isn't dead. I said maybe because it depends if Kishi gives a crap, much like Pain Arc, the one who close it are the one Naruto cares for the most. Kakashi helping him like teacher being proud of Naruto, foreshadowing of a best friend becoming a girlfriend, and a father-like figure being proud of his "son". Heck, if you go by the volume version, it even fade to Sasuke.
Now it is Kishi's fault for timing, because it happens so quick for her at least because again, you noticed that her resolution development happened in this arc, which sure took a while to happen. Let's say he concluded that moment back in the end of Pain Arc, then that's less screentime for her. But, because Kishi held it off for too long, everything seems to get complicated. Team 10 got their own stuff, so it's not like they were pending for previous developments. You can say Asuma is like a new one by Kishi. In a way, I still see myself him favoring Team 10 because they have in pending developments, but Kishi did it, let alone doing on the guy, who according to the poll at least, not even popular. Hinata was still waiting and it was a long wait. Now, she got it and then, uh oh, we have that phase that Kishi has to shine characters, so now it feels like she's getting two for the price of one, and it happens quickly in terms of gap. So yeah, Kishi's fault on timing.
Now, should you care? Eh, it's a bit too late knowing that she's about to get annihilated by Juubi, making a clean-up job to make room for Team 7 glory moments. I guess that's the point of the chapter to show everyone is about to get sweep. At the same time, it's about going out with a fight and always got him covered, which is why Naruto praises everyone. Sadly, this is the second chapter of the volume, so too early for comeback system, only downhill until reaching the end of the middle. Think as wrestling. The good guy(s) loses badly and hope seems lost, but then, a comeback happens and the good guy don't go down without a fight. Whether the good guy win or lose, at least he managed to fight back. Anyway, yeah, I'm not here trying to change your mind, just throwing my two cents there.
