No. The only way to give Hinata closure regarding NH would have been to have Naruto reject her, and if it only happens 3 years after Hinata confessed, then it just makes Naruto looks really really bad.
It's better to let it unanswered at this point, and consideres Naruto knew Hinata knew he won't ever like her.
If not, it looks like Naruto keep the titty girl around in case Sakura never answered his feelings. You know, as a consolation prize.
Naruto may be a bit of a Mary Sue that can force his naive beliefs on people, but he has never been a cruel manipulator at least?. Or someone whose cowardly behaviour hurts people, because he can't take a decision.
Don't depict him this way, pls Kishi.
That's not what I meant. I'm not saying it like Naruto kept Hinata as a bait in case Sakura won't love him back. More like Hinata still has hope for them to work out someway, although Naruto isn't giving her any signs for that. Sakura kept loving Sasuke although he made it clear that there is no interest in her. Hinata WILL need some sort of closure, that's the least she deserves. It could happen in the manga, but well, I think that's unlikely. That's why I think it can happen in the movie.
