But my biggest complaint in Naruto would be
1. Naruto needs more moves, I mean even after his wind manipulation, basically all he does is make a bigger Rasengen. (basically like going from kamehameha to a super kamehameha) Thats why I liked vegeta so much, he had so many different special moves.
Big Bang,Final Flash,Galick Gun yea that's alot.
2. You never know if someone is dead or anything. Seems like someone dies like 3 times every fight with these jutso's and what not. I usually just scan the chapter and see if they are dead, if they are then I read the fight. But otherwise it just pisses me off too much.
I haven't really come across a lot of situations in the manga in which the fate of someone wasn't clearly explained or shown.
