One of the basic ideals NH claims though is just that, its biggest weakness is the lack of development, people suddenly just expect all these blanks to be filled in and just somehow make sense.
Kinda like this:
-after her confession at pain and the results of the land of iron, people expected Naruto to just instantly start turning to Hinata despite Naruto not even mentioning anything to her, save what she listened to about him telling everyone about Sasuke.
-Sakura's still present love for Sasuke should have automatically been assumed to make NH and SS come true, because Sakura was not in the way to them anymore.
Yet there was nothing for years on the confession, the confession from Hinata has still not been addressed, its been longer than if Naruto still loves Sakura or not, and 631 basically hinted him still loving her. People just expected these things to happen despite no screentime, extended anime scenes, or even anime fillers come up to showcase anything. Yet we get a filler of Naruto still saying he loves Sakura but nothing on Hinata, still nothing. Doesn't that speak something funny? Especially now how things are set up? Unlike NS, NH is missing a lot of material. Some can claim the flaws in NS, but NS has a lot of an advantage because it has more screentime. NH is lagging and also without a major relevance to the main plot, people assume its suddenly more important than Naruto's own goals or that it deserves more attention.
615 was the real case that sent people into overdrive, people claimed it was canon or the start of canon, but as of right now, if it was canon Kishi just made some real issues to the story considering other characters were still unresolved I mean its not like Naruto and Sakura had all their interaction and development on each other said and done yet people acted like this was the end and that NH was set for canon, again dismissing Sakura's own development too. Basically they just wanted to jump to the end, nevermind the development of Naruto and Sakura which actually has a major reason near the end too, Sasuke. Hinata's involvement with Naruto has nothing in line when it comes to Sasuke. Something many fans seemed to have forget over these years is out of all characters in the series, Sasuke and Hinata are as far apart as it comes. They have no cause for interaction, they haven't even spoken to each other once save for the bonds movie where he tells her to go away. But thats just it again, in 615 NH was getting praise and that it was like the second coming or whatever, but then 631 comes up and then a massive freak storm is created and people question the events with Minato despite never realizing that the moment didn't and couldn't have resolved everything in just a few short panels. Basically if 615 was NH becoming canon then its really messing the story up with a statement like in 631. If it was the start of NH becoming canon, its taken off and swerved completely offcourse with again stuff like 631 and 633 bringing more of a reversion filler moment.
Its just at this point, where does Hinata go? 633 made things really unclear when we saw her acting bold and 633 is just seemed more filler than anything else. One reason I hate 633, its the one chapter out of the past few weeks that seems to have no relevance other than to show that the other members of team 8 and 10 are still around, yet we know Shikamaru has a decent role this arc even if its just been constant speaking. This chapter just doesn't fall in line with the rest and yeah it felt like an unnecessary filler. We saw this miraculous display of team 7 in 634 and 635 but the rest just does not fit with 633. So Hinata remains a mystery for now, thats not good or bad but it makes her hard to follow, something that makes a character not easy to relate with.
Hinata does have a clear endpoint though, gaining confidence and leading her clan, as for one of her major issues, yes its what her confession was to Naruto and how he reacts to it, but then again thats it, this has been unaddressed for just about 200 chapters. Now with this other stuff set in place like 631 and the lack of development NH has in total compared to NS, the lack of flow between development points as well, what is NH to do to suddenly merit itself as the most important or best developed when the series itself has become so limited and its nearing the end? How can it do this stuff now without filling in the blanks suddenly and assuming itself as the offical pairing when we already have a clue of this from Minato relating to Sakura, when Naruto's feelings appear to have not changed, and espcially how can it do this so it doesn't come off as weak as it would due to its lack of development, not upset Sakura's development, and not impede upon the situation with Sasuke? There are just too many issues, mainly for Sakura and Sasuke, they cannot be suddenly forced together either for SS just so Sakura's development is undone or completely putting Sasuke out of character. What are people going to expect? Some magic pixie dust makes people suddenly fall in love like from shakespeares a midsummers night dream? Sorry no fancy love jutsu in the Naruto series. Kishi can write his story anyway he wants but remember, what he writes is like a contract, breaking the flow or setting suddenly just makes things harder to understand or follow. He wrote Sakura being compared to Kushina, Sakura is the only girl compared to Kushina so far, to suddenly make Minato do this to Hinata or do it off of what we have seen, that just makes things more unclear. He gave us a clue with Kushina's last words, Minato built on them, so we should suddenly have Hinata in the comparison picture? Espcially when you can see who Kushina's past resembles? Thats basically the situation here, Hinata is suddenly not going to become some super powerful or centrally asserted figure much as fans would want. She isn't getting a powerup like Sakura, she is not part of team 7 as much as others wish she was. NH just has too many blanks and for them to suddenly be filled in, that makes it look weaker and rushed/forced. NH has a basis but its been left undone to years to the point Naruto and Sakura's relationship has gained enough development to be part of the underlying plot in terms of the story for team 7, the main characters of the series. We have had questions and gained answers for NS, still are, yet NH remains unresolved, if we got an answer of Naruto still loving Sakura past the land of iron events yet still nothing for Hinata defending Naruto, a situation even older than this, thats just not looking good for NH, Naruto didn't suddenly love Hinata and move past Sakura, yet others claim he did. Sorry does not work like this especially when we have seen Naruto focused on Sakura this long, its not going to dissapear as much as people wish it would. NS has its roots and has developed into one of the most developed relationships even as just friendship in the series, yet NH though it has its own setting and small amount of progress, its missing a lot when compared to NS and it just frankly cannot catch up at this point.
