Kishimoto has completely run out of ideas and is totally wash up as a writer. But as long as he have 75% of brain dead fans of his manga who give him a pass, he can keep using throw you off jutsu, to make that same 75%, not think it was the clear obvious person, in this case Kabuto (just like it was clear that Tobi was Obito after he told Kakashi his M.S eye technique wouldn't work on him), instead of making it look like someone else and then reveal someone new or out of nowhere character.
Then Kishi taint a proud Uchiha in Sasuke with Senju cells and give the most overrated main character of any manga, the other half of the 9 tail and the chakra of all the tail beasts, instead of taking the opportunity to make Naruto (the suppose reincarnated sage of the 6 path and if so the sage was a bum and I wonder if Naruto would of been the sage, if he wasn't born with the 9 tail fox) great without needing 9 tail steroids.
If Kishi wasn't wash up, he could of made Naruto have a different type of special chakra within him that let him manipulate the Juubi chakra at will and let Sasuke get the spiral sharingan that the Sage son had or the 10 tail Juubi sharingan and let Madara have the whole 9 tail with his other rinnigan eye, before Sasuke & Naruto tag team. But no Kishi do the obvious thing and have Naruto upgrade to 10 tail chakra and Sasuke get the rinnigan eyes, to team up on a one rinnigan and half 9 tail missing Juubi, sage of the 6 path Madara.
Kishi I already see your big genius wow moment at the end of your manga, when you let Naruto get the full power Juubi in him, to become the Sage at the end of him and Sasuke battle then Naruto defeat Sasuke and have all the Naruto Balls Boys go ape, before you let Naruto give the title and his dream of being Supreme Kage to your by far most goal driving character in Sasuke and Naruto succeed where Hashirama fail, because if you can't save one friend, you don't deserve to be Hokage right Kishi.
Kishimoto your the greatest wash up, obvious, juice every chapter manga writer ever.
