SAO was excellent here and there (Rudolph the Red-nosed Reindeer, The Black Swordsman, Mother's Rosario) and was at least decent all the way through.
It was just one of those series that became so commonly loved by normies that advertising one's hatred of it became an easy way to gain instant edgelord cred.
That was a great wrap-up — it settled pretty much every question I had about the story, and it was great to see Emi and Remilia face to face.
