The fact that he put the 'incorrect' in quotes indicates that he likely agreed with you on the use of the word and the you probably missed the intent of his use of it. Unlike 'bad', a subjective word indicating opinion, 'incorrect' is objective: anything can be incorrect according to a certain set of parameters, and the author is selecting a particularly traditional set here from the book in order to frame the discussion. He's not implying that Sonic is bad. He calls it a masterpiece! It's quite likely he's also a Lorde fan.
