the hashirama v madara flashback, the edo hokage, rikudara, the naruto/sasuke kyuusanoo, and 8 gates gai dont make for a good story. its just a tiresome long ass fight. and if it goes on for too long you start to lose interest. in fact it reminds me of abysmal the villain selection was.
juubi who's controlled by tobi who's controlled by madara followed by juubito followed by juudara whos controlled by black zetsu whos controlled by kaguya followed by sasuke, phew my mind is just exausted. forget this.
