I dislike SAO because:
-Of Asuna's sudden personality change to tsundere
-Asuna's and Kirito's relationship feels forced
-Kirito is overpowered and can break rules of the game because power of friendship and love
-Almost every girl in the show falls in love with Kirito because he's the main character
-Of stupid villains (One forgets why he did all this and another....He's a fairy butterfly)
-Of Yui, walking deus-ex machina
-Of how they still allow virtual mmorpg's even after hundreds of people died
-Of how Asuna and Kirito somehow survived when both of them were killed by the villain of the first half
-Of random timeskips, filler, bad pacing and much, much more
