do you have any changes you would make with naruhina?
In general I would strengthen the bonds between the rookies, I think that would solve a lot of issues (for Hinata, developing Team 8 and the Hyuuga more to give her a life outside Naruto - which was an issue with almost every character in part 2 - and for Naruto developing his relationship outside the Sasuke chase in particular, which I would have resolved by the time Itachi died to allow his character to breathe)
NH in particular though:
- actual interaction during the Uchiha Bros arc
- a follow up after her confession (not resolution, but a follow up)
- onscreen interaction after the war
I would also remove the timeskip in the last and have half the movie show them getting closer until Toneri happens. The seeds were there but I think the anime team had to scramble to both make up for Kishimoto’s faillings at developing romance and the need to have a Nardo movie have a lot of action and big explosions.
NH’s biggest problem was always a lack of screentime and Kishi being allergic to romance, not the relationship itself.
