I hate SAO, I hate the fact that it's dumb otaku wish fulfilment nonsense that barely holds itself together to form anything of a plot. I hate the fact that it feels like the show was designed by ticking boxes, rather than trying to tell a real story.
More than anything I hate the fact that it's incredibly popular, that so many people are so devoid of taste they mistake pyrite for gold. That anyone would call it "the smartest anime" and not burst out laughing immediately afterwards. That anime ranking lists would contain it, high up with real shows that could rival the best of live action. That newcomers would be told to step into it's world of mediocrity and have their standards forever poisoned by the sweet poison of a power fantasy.
SAO is a bad show, and you should probably feel bad if you think otherwise.
