Well, in response to you Hewitt, you're right. The technicalities of fights have been screwed over, albeit that may not be such a bad thing. I mean, it's a little over the top now but it would be pretty boring if the show was how it was meant to be; as in, actual stealth, missions actually going as planned, fights being jutsu - intelligent plan - win. And can we really blame Kishimoto? I mean, look at RHG's. We barely ever adhere strictly to the technicalities (Lookin' at you Zetabrand), as that would take the fun and creativity out of it, but it's a double edged sword as yes, they have recently become overpowered. The main problem with this is the inconsistency. Imo, by all means make Naruto have as steep a learning/power curve as you like, but don't make it that he learns rasengan in a week but barely learns anything in 2.5 years. An example of the steep learning bracket thing done right is Kingdom Hearts. Then again, the combat doesn't have any technicalities. Back on topic, my excuse for them is that Kishimoto is drunk on momentum. He's drawing this while hyperventilating and says, "Infinte chakra? Why the hell not?". While that may work for something like a movie or something that lasts a few hours, or heck, even one or two manga chapters, it doesn't work for an entire arc. Alas, nobody is perfect, and that goes for Kishimoto too.
