It's a forum about a fictional series lol, all debate here is essentially pointless if you want to look at it that way.
But if you didn't really want to debate, you shouldn't have accepted to take me on. You kinda made yourself seem like a fool by failing to refute any of my points.
-edit- I was only using the movie as evidence of Kishi having intended in the manga to parallel MinaKushi/NaruSaku and to show just how alike Kushina and Sakura are. While it should have been obvious from the manga itself already, some people were trying to assert otherwise, and this movie proves those assertions wrong.
The difference between fillers and this movie is that Kishimoto directed the story for it. Essentially, this meant that he was in charge of ensuring that the movie remained faithful to the canon. Aside from side characters that were deliberately given opposite personalities, the main characters were portrayed as Kishi had envisioned them within the manga itself, including Minato and Kushina (and of course, Naruto and Sakura). Authorial intent, my friend, authorial intent.
