I'm not questioning NaruHina. I'm pretty indifferent to it. If it happens then good for them. That's about it for me. I was more complaining about Sakura and Sasuke ending up, which would make zero sense on Sasuke's part. But people do change, though I wouldn't support it. No, my biggest complaint about the movie is the overall plot and how fillerish this villain we're getting sounds like. A descendant of Kaguyas? Well where in the world was this character when Kaguya and Black Zetsu could have used some help before they got defeated? This story only takes place one year after part 2 right? And this character's already strong enough to beat Naruto? What? Where was this character during the war arc? Why has nobody heard of him/her until now? This sounds like something a Naruto filler episode would give us.
