Belen Prieto Espinof Jul 21
4/5
Its blend of action, violence, institutional corruption, and ethical dilemmas is very well-balanced, and although its premise is extreme, it never goes overboard, which is appreciated. [Full review in Spanish] Go to Full Review

Teach You a Lesson is a thought-provoking drama that sparks meaningful conversations about bullying, accountability, and the hopes and limits of institutional reform. Go to Full Review
Suwitcha Chaiyong Bangkok Post Jul 6
Supported by natural performances from both the main and supporting cast, it is a thought-provoking series that keeps viewers engaged, regardless of whether they agree with using violence or not. Go to Full Review
S. Poorvaja The Hindu Jun 29
Do we have a winning formula on our hands? Or a possible second season that sees the return of the ERPB? Either way, this is the no-frills entertainment that has been missing from K-Dramas for a while now. Go to Full Review

7.5/10
Teach You A Lesson ultimately ends as a chaotic viewing experience. With its blend of action, comedy, and incredibly serious subject matter, it's a lot to take in, but it culminates in a mostly fun venture. Go to Full Review

S T @SMgolf 5d It is rare to see a great series from Netflix that does not promote gay lifestyle, has excessive f words, and too many DEI inserts. This series is all about justice for students who want to learn in peace and their teachers. See more Brannagyn T @RT97033995 Aug 21 Its rare programs are harmful rather than just bad tv. You expect an updated GTO or Gokusen with a rough & ready teacher coming to teach errant students some self-reflection and self-development but the first (satisfying) slap of a bully's face is the high point. After that you realize the entire extent of the shows approach is: hit children till they stop bullying, then humiliate them, then traumatize them (with a little more physical violence thrown in) and finally punish them with expulsion and public shaming. Ignore root causes & structural problems among students & teachers, just deal with a few bad apples. Ignores 50 years of educational/child psychology on the complex issue & instead offer a bizarre 1930s throwback where teachers are meant to be feared and obeyed and a good teacher is one who instills fear and discipline and nothing more. Ludicrously simplistic power fantasy that might come from a victim of bullying but not anyone who actually studied the issue in any way. See more John G @johngalt730 Aug 20 It had some high points, but like a lot of these Korean dramas, the last episode is a total letdown. Humor where there shouldn't be. Nonsensical behavior by the characters. An unsatisfying ending. There's barely any payoff for getting invested in the story. I understand that all Korean dramas are going to turn into slapstick comedies at some point during the show, but I was just fast forwarding through certain parts just to get through the slapstick scenes. Overall, it's probably a two or three star show, but the ending is just so bad that it colors the entire experience. See more G8 _ @RT70109312 Aug 10 Even though its not as close to the source material than iwould like but i would still enjoyed it the same as the source material and i really liked they added a romance to han rim and bong gun dae, anyways high praises and looking forward for the next season See more Kit L @Kitz_Editz123435 Aug 4 This TV show is so good! This show has entertaining action scenes, sad emotional scenes, and funny humorous scenes. It's like a sitcom with a great plot and great characters See more Judith J @JuJo678 Aug 3 It's very good.
