Belen Prieto Espinof Jul 21, 2026
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

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, 2026
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

Kelly C @RT62322239 3 days ago Absolutely loved this series! Every episode gets you emotional, and the pacing is so well done. It has a little bit of everything: comedy, heartfelt moments, and serious topics that really make you think. The story keeps you invested from beginning to end, and the balance between humor and emotion makes it such a great watch. Overall, an amazing series, and I definitely wouldn’t mind a second season! 🥹❤️ See more Kelly M @MovieLover700 5 days ago John Wick meets Dangerous Minds and 21 Jump Street. 😂 I thoroughly enjoyed it and the acting was great. See more tevita D @RT87911910 Sep 29, 2026 Honestly I really enjoyed Teach You A Lesson. The storyline was so interesting and kept me wanting to watch the next episode. I really like the characters and how the story showed different emotions and life lessons. Definitely a Kdrama I'd recommend if you like shows that actually keeps you interested.[Please let there be a season 2] See more J R @RT91837970 Sep 27, 2026 My wife does not like K-Dramas but after watching the first episode…SHE WAS HOOKED!!! And so was I!!!!! Great cast and story line and we love how they stick to real world situations!!!! This is a problem In the school systems everywhere- THANK YOU FOR NOT THROWING IN GAY/LESBIAN LGBTQ WOKE CRAP IN IT!!!!! That is all that the U.S. directors can seem to do nowadays and ruin good plot movies and tv series when they throw that crap in it!!!! CANT WAIT FOR THE GREENLIGHT FOR SEASON 2!!!! See more Arthur M @mosssfrog Sep 25, 2026 I expected a fun romp where an unconventional teacher reshapes a school, but instead became morbidly fascinated by a show which endorses an absurdly authoritarian, pro-corporal punishment fantasy in which hitting children improves their behaviour (it does not), teachers are victims who never abuse their power (they aren’t) and no attention at all is paid to why kids really behave poorly in schools. SPOILERS In episode 1 we see strong parallels between how the bullies treat their victims and how the main character treats the bullies, but this is never examined with any degree of self-awareness. Episode 3 in particular is terrifyingly mask-off, as a tender hearted teacher who was previously beloved by her students canes a girl while tender emotional music plays, as if this is a beautiful moment. I can appreciate tv that’s detached from reality fine, but this entire show is a ridiculous fantasy which contrives itself at every turn serve a ridiculous pro-harming children narrative. See more S T @SMgolf Aug 29, 2026 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 Read all reviews
