This, my friends, is why I loathe time skips. It is the ultimate writer escape hatch. They don't have to explain how anything happened, they just need to say that stuff happened during the time skip, and we're just supposed to accept it.
In reality, I have virtually no animosity for the movie. It will have nothing to do with determining the final pairings because the manga will do that. In a way, I like the idea of using a movie to give Hinata some closure if NaruSaku happens, since there probably isn't enough time left in the manga to do it. I don't hate her character itself, I just don't see her as having any chemistry with Naruto. In the end, chemistry is what matters, not which two people physically look cute together.
Part of me is torn. On one hand, I hate that Kishi keeping the resolutions down to the last minute has caused the fandom to reduce itself to screaming at each other. But on the other hand, part of me kind of likes that the final pairings were not obvious from Chapter 1. Definitely keeps the tension up. But I guess I'll end up hating it if NaruHina wins. In the end, NaruHina is not even close to being as developed as NaruSaku.
Hey, new guy here. I just wanted to present one of my theories on the movie to see what you think. I think the scene between Sakura and Hinata might be Sakura giving Hinata permission to do something nice for Naruto. Perhaps Naruto and Sakura are already together, and Hinata was worried that Sakura would take Hinata doing something for Naruto the wrong way. This is probably false, and I'm kind of pulling this out of my ass, but I just wanted to put it out there.
