Why do people say Kishimoto's writing is horrible?

[Narutohokage324]

"One of the running themes in Naruto is that no one is born evil, everyone is capable of redemption, and it's better to offer friendship to the villain than to kill them (even if you have to beat some sense into them beforehand). The track record for this one arguably starts off the best and most consistently of any of the story's aesops, however it began to break late in the story, again largely due to the Uchihas. Every member of the Uchiha family is viewed as a friend who is simply walking down the wrong path by Naruto, anyone like him, and the general narrative of the story regardless of what crimes they actually commit. On top of that, Madara and Sasuke do nothing with these chances at redemption than use them to become more evil and attempt to gain more power for themselves. And this only really seems to be for the Uchihas, with non-Uchihas like Hidan and Kakuzu both being killed (Hidan being essentially buried alive) without being given even a single chance at redemption, much less the dozen or so Sasuke alone got."
