You mean the hero's role right? Hinata and her clan are even stealing Naruto's spotlight in this movie. Naruto seems to be a secondary character who's only purpose is to be the guy who fall in love with the heroine and to save her.
This whole movie looks like a big birthday present to Hinata, it's a big excuse to give her all what she always wanted, even if it has to give us the worst movie ever and neglect every othre characters, look what they have done to Kakashi and Sasuke, they are barely important in that movie. And I'm not biased when I say that, I have no problem with NH anymore, but seriously, what kind of Naruto (or any shonen fan) would want a full movie about romance, except if you're a NH fan?
this makes me laugh cuz it's completely true
I'm pretty much sure that even SS won't get spotlight (as per needed)
Only NH fans (specifically those who didn't notice some contradictions in ending)
will definitely watch
others ... I dun think they will
