Why do you care about the movie? NaruHina fans are hyping this up, but they don't understand anything or the consequences of supporting the movie.
Hinata was rejected by Naruto when they were kids and this makes her cry. It traumatizes her enough that she isn't able to give him a scarf 10 years later. NH fans have been saying for years that Naruto makes Hinata strong, that she got braver after the confession, that she would have died for him. However, in the movie, Hinata cannot give him a present. This is pathetic and weak of her, and she's like this because of Naruto.
Friends give presents to each other, but Hinata can't do even that. This means they're not in a relationship. It also means that Naruto isn't in love with her, even after everything that happened between them in the manga. Sacrificing her life for Naruto and confessing her love? Mattered not. Supporting him against Obito and giving him courage? Mattered not either. She's still just his friend. Remember all those arguments that he was considering her love confession and that's why he didn't answer her confession? He wasn't. Nobody takes two years considering if they should date someone.
It also implies everything that happened between them was platonic from Naruto's side. Going Kyubi on Pain? Platonic. Handhold? Platonic. Yet NH fans said otherwise. That Hinata confession made Naruto love her. That Naruto saying that he saw her feelings in her eyes, was a hint that Naruto loved her. That the handhold was yet another hint that he loved her. That him reacting to her thinking of him before entering IT was the final hint that he loved her. But none of that is true if we are to believe the movie's advertisement. Their development (if we call it that) might have made them close, but it wasn't romantic, like we've always said.
Even if NH is made canon in the movie (doubt it), it means they got everything wrong but who ended up with who. All the development (if we call it that) and all those arguments NH fans babbled for years were irrelevant. Naruto didn't fall for her because of anything that happened in the manga, and that's hillarious. NH fans always said that their development and relationship and moments made their ship canon. It's not true. Nothing that happened in the manga mattered outside of making them close. It took two years (so not connected with the manga's plot) and a filler movie for that to happen (and I'm saying this if it happens, which I doubt).
I'm a Sakura fan above everything. I'll be happy with whoever she ends up with, as long as she's happy. As an ANH fan, this movie pleases me and I don't get why NH fans are happy about it, since it proves ANH right about everything we've always said and NH fans wrong about everything they've always said, with the exception of who ends up with who. All they'll be able to brag about is that they end up together. They will celebrate that and kitten, but to themselves? Bitterness. All their nonsense arguments supported by the manga are irrelevant and wrong. All their LAPs and essays? Wrong.
Unless they're really just that stupid.
