Double-posting cause screw it *^*
You'd have to be blind or delusional to think Boruto is something Totally new. XD
Well to be totally honest, I'll just spin it backwards.
Boruto doesn't care about being a shinobi, in as of now he doesn't have a goal. In the future though, he wants to become a support system for the Hokage, following in his Master's footsteps.
Boruto is a Ninja Prodigy; Talented and far smarter than his father at his age.
One of the biggest defining differences from Boruto (and other characters too), is that he just plainly gives up when he doesn't think he can go through with something all the way.
Boruto is extremely lazy, to where he doesn't like to train at all. This also accumulates to school.
Boruto doesn't care when someone ridicules him, he doesn't get in their face.
Boruto's fighting style is a lot more refined than his father, relying on strategy and ninja tools, because he lacks large reserves to spam shit without thinking.
And since you were taking about their styles, I think the fact that Boruto unlocked his own Dojutsu (Something Naruto never obtained), and a Mark (or Curse Seal?) separates them further.
Can you tell me how any of this is 'Naruto' -- I wouldn't say most of this is unique, but rather, most of their characters are either combinations of their parents. Or just opposites of their parents. Boruto being the latter.
I don't mean to be rude either, because your points are just as valid as mine, wrong or right. But I feel like you skipped or glossed over Boruto's characteristics or something. W/e tho
