Kakegurui blowing up is pretty damn astounding, mainly because its main focus is gambling but there it is. Goes to show how objectively strong character designs and good direction can make an appealing impression to casuals.
I'm surprisingly tore on Netflix's acquisition of MHA, on one hand they may have done Toonami a favor taking away yet another shonen series from the already saturated block. But on the other, with how popular the show is becoming and depending on if we would have gotten it this year, we possibly could have seen the successor to OPM.
Definitely, with the addition of what's in store for 2018, Godzilla, Devilman Crybaby, and their original anime, Netflix really knows how to pick em'. Maybe violent and dark anime with interesting concepts are the way to go, Demarco should take notes. Hopefully he'd learned his lesson from this crisis and will put the future of Toonami over giving the loud majority their fads (I am looking forward to IBOS2 though).
Edit-Arguably Jojo part 3 and some other shows fit that description but apparently the general audience doesn't see it!
