Asuna almost got free only to be stopped by tentacles. The feeling was icky and made me cringe more than Silica's episode which is more humorous and carefree.
Kirito is too much of a Gary Stu with his illusion magic when he assumes the form of the Blue Eyed Demon. In episode 22, he got too cocky when he tried to go solo.
Lot of fans hate Suguha for being selfish. I don't think she is. Unlike the other girls who are passive, Suguha struggles to bury her feelings for Kirito knowing that Kirito loves Asuna. When she finds Kirito is her cousin, her heart is torn apart.
Episode 22's animation was stellar. Love the guardians and their fight.
