Like I know you hate Sword Art Online, and let me say that SAO is comparatively quaint and wholesome and well paced and well thought out next to the absolute pile of flaming garbage that is Made in Abyss. SAO is poorly written slop that's good enough that it can be laughed at for how bad it still is (and its spinoff series that was written by an entirely different author is actually almost good although still bad and problematic). Made in Abyss is just an abomination that should not exist.
