I just finished watching all 12 of the episodes today and oh my god. I'm in tears. Not only because of the ending and the ships. But rathe because of how well the anime was organized compared to SAO and SAO II. In my opinion, nothing beats the original which is normal Sword art online(Aincrad, Fairy dance, phantom bullet, caliber and Mother's Rosario.) I'm not counting aliziation since I don't really like it that much. But when it comes to main characters, I definitely enjoyed LLEN's character more than Kirito and Sinon. However, the character Death Gun was fairly interesting though there's just something with GGO alternative's villain which is Pitohui, I'm not going to spoil why she's so interesting to me but I definitely enjoyed her ruthless nature. I'll publish my real thoughts in my: "Fandom Talk" Book. Cya! And do I recommend the anime? Heck yeah!
