I quoted a specific area for a reason. Did you not read which area that was?
Naruto doesn't handle themes better. It's sloppy and all over the place. It has too many characters who serve no purpose and take up too much screen time.
And side characters can be killed off to make the characters grow, but the immense number of them that seem to exist for no other purpose than to die lends more to them being cannon fodder so the main characters are never at any real risk.
Those two sentences contradict each other. It's in a magazine for pre-teens/teens, yet the developers suggest it's a mature/adult show?
No. It isn't.
