I go by story arc. Arc 1 = Aincrad. Arc 2 = Fairy shit. Arc 3 = Gun gay. Arc 4 = Alicization.

I assumed the "season" numbers followed the arcs but I guess not. I was shitting on the Fairy Arc and Gun gay online because I thought those arcs were pretty dumb. And yes the whole "sister tryina fuck" fetish shit is cringe, and the main villain was over the top.

Haven't watched Alicitzation but from everyone I trust in their recommendations, it's good so might catch it later.

It has dumb shit in it but from a technical perspective it's the best season, though it's 47 episodes and basically half the total. It feels like the author put in more effort.

I stand by that SAO Abridged is doing season 1 better

I can't stand the main character's voice. It's a grown ass man who sounds like someone just kicked a baby in the balls.

I really liked Hellsing Abridged, though. Goblin Slayer abridged is also good based on the MC's voice actor alone.

It's hitting it's peak now thanks to stuff like Mushoku Tensei

My GF hates Mushoku Tensei because the MC acts like a sex offender. He doesn't do anything IRL but his thoughts have really creepy hentai shit sometimes so she got disgusted with him and was like "fuck this guy". It didn't help that the show played up the "haha it's a middle aged man in a little boy's body who can totally fuck lolis 'his own age' and get away with it!" angle.

Most isekai are filler trash but they're the best filler trash. Most anime trash is unwatchable for me, but isekai trash is at least watchable because they come up with magic systems, combat mechanics, etc. Most of it is bad but sometimes there are interesting ideas.
