I dropped SAO after season 2. Well, didn't actually drop it, s3 wasn't out yet and i just never went back when it did. It's been like 5 years. I'm gonna start season 3 without rewatching the first 2 seasons, wish me luck. I have no idea what the plot was about :BucketHeadYui:
it's better then the 1st season, but honestly I think the whole show is mid. don't get me wrong I love it, but after season one it pretty much could only get better. the animation, voice acting and plot get so much better. I love season 2/3, much much better then the first! the characters feel much more fleshed out and the universe is expanded
oh! and whatever season starts in the fairy RPG is so good because there's so much SA /R*pe-y content. I love recommending SAO
