There shouldn't be anything childish about shinobi with weapons too kill or protect ones self from being killed!.. This manga/anime is an has been dark from the start to me.. (They're shinobi that kill or be killed for their believes) I don't mind him dumbing it down abit but what's the point in that when he's using the artipel ninja/shinobi, there's no childsplay or child like scenarios with shinobi.. (Rated Mature)
Naruto & Sasuke are going to be set aside or nerfed really bad for this next gen to fit.. (NS ended with the power scales to high for the main protags so it will be bumb down alot for them but probably with different tech's mixed with old for the new gen..)
He did say he didn't want a copy paste of Naruto's gen so that maybe the only thing that I stick around & check it out awhile to see the results of.. Other than that, this new gen just don't have that appeal that the last gen of shinobi..
All my rambling aside though.. I'll read/watch wait an see how it goes..
