Failed Potential. Kishimoto should have build up Sasuke as a turn villain. The foreshadowing was already there. Sasuke was the new Orochimaru. Kishimoto even gave Sasuke his own minions in Shippuden. Sasuke should have gone full dark side. Naruto should have learned that talk no jutsu doesn't work and should have gave up his ninja Jesus beliefs and killed Sasuke. If Kishimoto had written Naruto this way then the show would be remembered as the best Shonen, even above DragonBall.
