Here is my honest opinion on the matter.
I like Naruto as the character he is and compared to Sasuke, he is more interesting in every single way. BUT, right now, the story IS wasted on Naruto. It is a sad fact.
Since Part 2 started here is what Naruto has done.
Angst about Sasuke.
Angst about Gaara.
Complain.
Complain.
Angst about Sasuke.
Complain.
Go on a Kyuubi rampage because of angst about Sasuke.
Complain.
More angst about Sasuke.
Train again.
Beat Kakuzu in a stupidly short fight.
Angst about Sasuke again.
Angst about Jiraiya's death.
Complain.
Complain.
And now train again.
Does anyone else see how stupid this is? He is the damn main character and he has done NOTHING but bitch and complain the entire time. It is becoming a joke now. It actually makes me wonder what the hell Kishimoto is DOING. Compare that to Sasuke who has wiped out two Akasuki members and Orochimaru and is now going after the Eight Tails. Sasuke has accomplished infinitely more in his short time back then Naruto has all of Part 2. Naruto has had NO real fight in Part 2 when he had about eight in Part 1. So yes. It is a shame, but Naruto has done nothing at all so far and the story is wasted on him.
