Very sloppy writing, but holy cow the level of acting is quite intense. If you enjoy watching (or scouting lol) relatively obscure young actors battle it out, you'll be able to tolerate the massive gaping plot holes somewhat.
Stand out performances: the lead duo Nezu (can't believe dude is JE member, strong candidate for "I Can't Believe He/She Can Act Award" this year) and Inukai (no surprise), Yamaguchi (that epic long take in ep.3 - Beast Performance), the Youtuber dude (forgot his name), Reika (the rebellious girl).
things like Mikio's two videos before and after his experiment in making nezu kill him failed and him saying that…
I concur. For someone uninterested in reading the original material, not revealing the motives of the teacher is bonkers decision by whoever writing the script.
I've heard there are short spinoffs out there, depicting the back story of some of the characters, which explain their underlying motives and set the stage of the events in the main series. Perhaps it does shown in one or two of the spinoff episode but who knows. And that being said, they should've retained that in the main plot anyway because it's so important.
Bloke impressed me in Nare no Hate Bokura. Perhaps his first relevant work to date, albeit being not the main character and the show itself is packed by great performances from relatively lesser-known actors. Will keep an eye on him.
why did they make it less violent?? like in episode 3 they were supposed to be literally crushing the girl's hand…
Didn't read the original material, but I reckon the show might've been more interesting with more Mikio-Yamaguchi combo lingering longer than what it's shown here. Great chemistry and dynamics, albeit brief, between the actors too. Can imagine the duo trolling and putting even more pressure on the rest of the class during the ordeal, where the latter acts in opportunistic manner.
Trivia: both actors of these characters appeared together in Kimi ni Todoke with radically different roles and interaction (see my comment below).
There is no doubt that Inukai-kun is the man of a thousand faces. hard to believe that just a few weeks ago Inukai-kun's…
Just a few months ago I saw Inukai and Riho (the one playing the bullied girl) playing a gentle dude and a feisty girl who had a childhood crush for him, respectively, in light-hearted Netflix' Kimi ni Todoke. Here they play much more primal roles and both do it superbly.
She is so beautiful and talented. I have watched her in Kimi no Te ga Sasayaite Iru and Uchi no Musume wa, Kareshi…
Itoshi Kimi e, Kiina, Hataraki Man, Sakuran, Dolls, Koi ga Shitai, and if you can get to watch it, 100 Tales of Horror. Basically 90% of her projects in the past.

If done right, Haruma would smile from heaven up there.
