I feel the same way. In the beginning, no - all the way up to just before the Invasion of Pain, I think Kishimoto was handling Naruto's Character & Strength Development well. Sure, we found out the Uzumaki were related to Senju/Rikudou but probably to intensify the rivalry between Naruto and Sasuke. And then thr Invasion of Pain happened and we found out that Naruto is the Child of Prophecy.
Oh Jesus Christ, why? First, to Neji, Naruto says that there is no such thing as destiny or whatever. Then he finds out he is a Child of Prophecy. So he is basically assured victory as Naruto isn't going to destroy the world, unless Kisimoto wants to make Naruto just like Anakin.
In that same arc we found out that Yondaime was his father.. Why?? He was the loser - the runt of the litter. The little bastard that had no skills whatsoever and through will power and sheer training, he outclassed most of his age group. And then we find out his father was this super OP shinobi.
Then we see Sage Mode in action. Great - it has many disadvantages and risks but still powerful. Great power up - then this guy gets KCM and BM. Sage Mode put him at Kage Level so he is still human - KCM and BM place him at a tier unmatchable by people like Kakashi, Guy and Lee. Honestly this series has become a bit contradictory.
Look at the average Top 10. Let's see what characters they have..,
Hashirama, Madara, Obito, Naruto, Nagato, Itachi, Sasuke, Minato, Kabuto, Killer B
Hashirama, Madara, Obito, Sasuke and Itachi and arguably Naruto and Nagato are from a blessed clan. Naruto and B are Jins. Kabuto has the cells of various people. The only one we have that isn't special is Minato and rest assured, we will probably find out that thr Namizake are important.
Well sorry for ranting - I agree.
