    Opposite to the title, the drama is strong and brilliant

    Weak Hero Class 1 is a high school thriller series that follows the story of 3 students who doesn't care about anything else, and somehow gets involved in constant fights due to bullying.

    Most of the school centric dramas are romance, which becomes monotonous watching after a certain point of time. Weak Hero Class 1,however, is a thrilling, yet sobering portrait of young students and the different struggles, difficulties and momentary joys they experience while growing up in a society that, too often, neglects and pushes them aside, that successfully stands out as one of the best dramas of 2022.

    With just 8 episodes, the pacing is superb and the action sequences were well crafted. And perhaps what the series does best is to show the immeasurable toll such violence and abuse can take on one's physical, emotional and mental health. Especially for teenagers who may be experiencing other types of abuse, hardship and struggles outside of the school walls as well.

    School violence is certainly not a new theme for a K-drama. But Weak Hero Class 1 is able to take that familiar topic and present it in a way that focuses more on the characters, particularly the victims, and show the unfortunately lasting effects of such violence. The best part of the drama were the 3 leads who had an amazing chemistry on screen and their change in characters once the events turned dark.

    Adapted from a webtoon, Weak Hero Class 1 is engaging, highly effective action packed school based drama. The finale teases a 2nd season and yes I am very much intrigued to see what happens next.

    My Rating : 8.5/10.

    I will never see a pen the same way again

    The story is typical. Some rascals bully other weak students in school. But don't give up on that, because our protagonist, Yeon Si Eun, although has a weak physic, has a brilliant mind in fighting comparable to Sherlock Holmes (2009 and 2011) type of fighting skill.

    Si Eun fought bullies with his wits and will. And along the way, he picked up some new friends. Soo Hoon, Beom Seok and Young Yi joined Si Eun to end bullying in their school. And when they thought it was over, something happened among themselves that beyond anything they could prepared for.

    I binged watching this last night. A full 8 episodes of brawl, friendship, love and betrayal. And I just can't wait for season 2 already!

    Excellent 9/10.

    Season 2 of Weak Hero Class Left Me Speechless - Season 3 Is a Must

    I honestly don't have enough words to describe how much Season 2 of Weak Hero Class meant to me. It's rare to find a show that hits so hard emotionally while still delivering intense action and brilliant storytelling. Every episode had me completely hooked - I felt every punch, every tear, and every quiet moment. The characters grew in ways I didn't expect, and I found myself caring about them even more than before.

    This season wasn't just good - it was unforgettable. You can feel the passion and effort behind every scene. That's why I truly believe a Season 3 isn't just something fans want - it's something we need. There's still so much more to explore, and I hope the creators know just how powerful this series is.

    Unexpectedly Great

    I went into this show with admittedly low expectations. It didn't air on any of the big Korean channels, and wasn't made for any streaming service in particular. There were no big name actors in it, although I did recognize Park Ji Hoon from the fantastic At A Distance Summer is Green, where he played a summery playboy hiding a dark secret. This character could not have been more opposite, and boy was I blown away by his performance. I hope he is given bigger roles after this show, he certainly deserves the chance as his acting was great across the board.

    Si Yeun is a pretty, smallish young boy, so seeing him being a brilliant strategist combined with a wiry, stubborn strength was a pleasant surprise that kept me interested from the very first few minutes. While school bullying in Korean dramas is certainly not a new concept, this show is somewhat different from the others I have seen. It centers on human emotions in a way that puts every character in a grey moral zone that makes them all incredible interesting to watch and also all too relatable.

    It seems the ending was set up for a season two, and I really hope to see another set of episodes of this amazing show. I was completely hooked from start to finish!

    BEST KDRAMA 2022 FOR REALLLLL

    Ok i watched many many kdramas this year BUT WEAK HERO BEATED ALL OF THEM WALLAHI I COULDNT MOVE ON AFTER A MONTH EVEN WHEN I TRIED TO WATCH OTHER DRAMAS PLS HELPPPP WE NEED SEASON 2.

    So what i like the most about this drama is just that the storyline didnt tangle a bit, you will watch the entire set of episodes in just one sitting because please its hard to stop the screen i swear. It ran so smoothly that i couldnt even wanna close my eyes to miss a very tiny bit of a scene. Some actors here may not be recognised by most people yet they could prove them they all acted as in theyre professionals. THEY AMAZEBALLS IN ACTING, all of them. Sieun may impressed most pf you but they all actually did. They didnt have many unimportant chats, they used emotion strongly and actions or fights as needed. Not over. What i love about the main of main, SiEun, is that he had kinda adlibs, when he did the slaps himself, it was his idea, same like the glass breaking scene. He just told to do so yet hed improve the action more than the director ask him to. He were possessed by his characters many times so youd amazed by how strong his feelings would touch you.
