I can't seem to remember the exact chapter but for me it was during one of these scenes, during the Fourth War, where Minato commented on Sasuke's power and mentioned that Naruto had not yet matured like Sasuke did. In my head I was just like "Did this mofo just say that Naruto, who suffered because of something YOU did to him and somehow managed to become a sane, albeit slightly childish adult human, has not yet grown as a person?" I was done at this point. I mean, it was a combination of a number of things and by that point I had also stopped watching the anime but that was the final straw. Anyway, which scene did it for you?
