This movie has been in the making for like a year or so, right? So if that's the case, why did Kishi not allude to NH in the manga at all? Why did he not make 615 a turning point for Naruto's feelinngs, but instead show that Naruto still holds a romantic interest in Sakura? Why did he not allow Hinata to reach Naruto, yet Sakura was able to remain by his side, even thought she was not the intended person Gaara was trying to get? Why did he make Naruto bring up the POAL, when the last we had heard of it was in the LOI, where Naruto said the promise was the reason( or only reason, can't remember) why he was going after Sasuke, leading others to believe it no longer held importance to him? Also why hint that Naruto would confess, once the promise was fulfilled, if he was never going to do so?
The movies advertisements contradict the manga in many ways, since it's pointing to NH. Meanwhile, we're not even getting info on the villain or even Naruto, just about Hinata wanting to give him a scarf and being abducted. It's weird to be so obvious with the romance plot, but not the rest of the movie, especially, when the manga is pointing in a completely different direction.
We'll get most of our answers next week, so until then I would not be worried.
