Let me say something. The premise of Naruto is love and peace, and its core can't be avoided. It needs a corresponding theme.
This is hard to explain clearly all at once.
Or rather, explaining it would only muddle things, so they can only arrange a savior, drop a god out of nowhere, and have everyone unite against an outside enemy. It's the standard Japanese-manga ending: putting aside hostilities to fight the evil BOSS, with friendship, youth, passion, and everything else thrown in. Mutual understanding between people, and some things that look beautiful and embody the King's Way.
It looks like the world has changed, but once you peel it open, nothing has changed at all.
Bloodlines and royal authority run rampant, while feudal ignorance is horrifying.
It's childish and clichéd.
In the face of this ending, the cruel conflicts that the early Shinobi World spent so much time building up, along with its various themes, are nothing but a joke.
And there is more than one joke.
I've gone a little off topic.
I'm writing this in comparison with the whole of Naruto.
The structure is basically symmetrical.
Many details are the opposite.
For example, Naruto talks about people understanding one another and letting go of hatred.
But here, it seems no one understands Nami. No matter how much she does in silence, everyone can only fear Nami's power.
Naruto talks about effort overcoming genius, but in reality, effort isn't as useful as a good bloodline.
Here, talent seems to represent everything on the surface, but in reality, the greatest hard worker in the Shinobi World is Nami herself. Knowledge is power. Nami herself is utterly unremarkable, yet she uses a single fulcrum to lever up the world step by step.
There are many more comparisons like this.
