Re: Neji was RIGHT!
It's not that Kishimoto has become a worse writer (say what you want, Shippuden isn't a BAD story) it's that the themes of Part 1 Naruto have become twisted beyond recognizability.
Part 1 commented among other things on what loneliness and isolation can do to a child (or any human), what reasons for seeking power can be forgiveable or even admirable, what excessive hatred can drive you to do, how some things are more important than any rules, how hard work and determination can and will give rewards, how promises can matter in a way the world seems to have forgotten, how bonds between friends and family are made and broken (but never truly gone), and how both maintaining bonds and breaking them offer their own versions of power.
Shippuden has ignored or revamped a large amount of these beyond recognition, though some themes do remain. Kakashi's nindo, for example, (some things matter more than rules) has remained stable even throughout the greatest emotional trauma he's ever faced (it's at the very least high up there). On the other hand, he did need motivation from Naruto, and the next paragraphs will explain why I loathe how Naruto keeps doing things like that.
One theme (which may not be intentional) running throughout Shippuden is how ONE PERSON should not be allowed to change the course of the entire world. Isn't this, if anything, the greatest reason why the ENTIRE shinobi world has united against Obito's and Madara's Moon's Eye Plan?
That if lasting peace and happiness can be achieved, it CAN NOT be through the work of ANY single person, not even someone with powers almost divine in scale (Nagato, Madara).
Peace must be achieved through cooperation. Not EVERYONE in the world can be expected to work together, but if ENOUGH do, the battle will be all but won.
Naruto doesn't think so. Naruto thinks that it's okay, even ideal, that ONE person is responsible for the entire world. He can't go on thinking like this, it can't end happily. If he thinks that HE should be the SOLE protector of how the world should be, he will become worse than Madara ever was.
EDIT: This is also why I find the idea of Superman utterly detestable.
