It seems that you do not know the whole story, if you judge only by the anime, then everything is clear.
Moreover, it would be foolish to expect super plot twists and something from a young and inexperienced author like Reki, however, it was not even supposed to be there, this is how repulsed one must be, first. Second, about the "harem" and other things, I have already said earlier, bother to look, I have no time to repeat.
Thirdly, the same Kirito is no better and no worse than other characters, absolutely, and show senseless aggression towards him? What kind of nonsense, then let's hate all the characters in general, any works, just like that, but what? this is exactly what it looks like.
And lastly, to compare a cult work with a craft, I repeat, of a young and inexperienced author? You couldn't think of anything else?
