To all of those people that think Naruto is dumb: I understand that in the beginning of the serius everyone was sterio-type but as it goes on you understand what these charecters are going through. Like Naruto, he totally acts like a clown and idiot but later it shows what he went through. Same for alot of charecters. And if you watch the show long enough then some episode you will start crying. So it's not a dumb show at all. It's actually pretty great.
-Violence- depends, sometimes it's really violent and scary(japenese version has quite a bit of blood) but nothing that bad unless the episode has a violent theme.
-Language- like always, japenese has pretty bad(damn,idiot,stupid, and VERY rarly the f-word and s-word) the english doen't have that bad.
-Socail- Charcters change ALOT throughout the serius, so no worries, unless talking about villians.
-Sex- Naruto has this tequnique that turns him into a naked girl(nothing shown) and that about all for him(he stops using it in Shippuden(part 2). But he has a teacher, Jiriya, who id OBSSESED with woman and every time he is in a episode, he tries to flirt with at least one. Regularly nothing there in most episodes though.
