i read the first 6 ot 7 lines and it's refreshingwell, I bash Naruto all the time although I use to love the character. As mentioned before he is the way he is because of the way he was brought up in Leaf and most people dont mind his attitude in general just his attitude being a ninja. What I mean is that he is a ninja yet he acts and prioratizes situations like a 15 year old girl in love, oh wait.. he has a 15 year old girl in love in his team that doesnt act like him... see what I mean?
When it comes to his development, of course people will be mad... common, he trained 3 years with the man that trained the 4th and Pain... and he comes back after his training not knowing the full extent of Kagebunshin (knowledge transfer when dispell) or not even knowing about elelemtal chakra or chakra recomposition???!! Jiraya spend 3 years with 3 Rain kids WITHOUT KNOWING HOW TO EVEN MOLD THEIR CHAKRA and in that time span they ALL learned how to use elemental jutsus.
I mean just how dumb can Kishi make Naruto. For all this things NOT to happen for Naruto during a 3 year 1 on 1 training with one of the strongest, if not the strongest, ninja and/or teacher in the Narutoverse. How can fans not be mad at Naruto lack of growth as a character and as a ninja??
Most likely I would get flamed by this but if it wasnt for Kyuubi, because of Naruto dumbness and lack of growth, personal and professional, he would died a long time ago. I have always said that I dont consider Kyuubi a "cheat" since he has had it from birth but Kishi is pushing it... even after the true reason behind his "speed of learning" and winning is Kyuubi (Rasengan wouldnt have been learned so fast if he couldnt heal and recharge after spending all his chakra and damaging his nerves after just 1 goodnight sleep, every major battle has been won after accessing Kyuubi's chakra and of course the reason he can train like he trained to achieve Fuuton-Rasengan) Naruto not only seems but IS in fact still the same Naruto as when he was 12.... it is not only dissappointing but a little sad as well.
Of course this is just my personal opinion ;p
OH PS I mentioned before as soon as I saw that Naruto could possibly be the new "Chosen One", that Kishi will mess his own manga if he does. His manga has always been about hard work, to quote the manga itself, "a drop-out WILL beat a genius with hard work" and conserning destiny "it you think its impossible then dont do anything" and suddenly will changes to making Neji right, "Destiny cant be changed, everything is chosen since your born".
