Reasons To Watch “Queen Mantis“
A never-before-seen concept in K-Drama
“Queen Mantis” is unlike any other K-Drama we’ve seen before. Instead of the typical lead character, we’re given a complex and chilling anti-hero: a female murderer who doesn’t just kill one person in a moment of rage but five people across a calculated spree two decades ago. Known as “The Mantis,” she became infamous nationwide. Yet what makes her story even more compelling is that all of her victims were corrupt or abusive men who had hurt others. In a twisted way, she positioned herself as an avenger for people who had no power to fight back.
Now, fast-forward to the present day. A copycat serial killer resurfaces, imitating the exact same style and method that made The Mantis infamous 20 years ago. With public panic growing, the police are forced to seek her expertise. But she agrees to help only on one shocking condition: the investigation team must be led by her estranged son, a police detective who despises her and has tried to distance himself from her crimes his whole life. This explosive setup makes every episode feel tense and unpredictable, as mother and son are forced to work together while battling years of resentment and mistrust.
A Well-Written, Thrilling Mystery
One of the best things about “Queen Mantis” is that it doesn’t just rely on its unique concept — it actually delivers on it. The writing stays strong from beginning to end, keeping viewers hooked throughout its eight tightly written episodes. Each episode is packed with twists and turns, making it impossible to predict what will happen next. Every week, we’re introduced to new characters, each with their own secrets, and the show cleverly makes everyone look suspicious. You’re constantly second-guessing who you can trust, and that tension is what makes this drama so addictive. It’s also impressive how every scene connects to the bigger picture — the way the secrets slowly unfold will leave you gasping in shock.
For those who don’t know, “Queen Mantis” is based on the 2017 French series “La Mante.” While it draws inspiration from the original, the Korean adaptation brings its own flair, with stunning cinematography, a more layered backstory, and a fresh approach to the characters. With only eight episodes, it’s perfect for binge-watching, especially if you’re looking for something unique, tightly paced, and thrilling from start to finish.
Stellar Acting That Brings the Story to Life
This drama also excels in the acting department. Headlined by Ko Hyun Jung as “The Mantis,” we get to see a side of her we haven’t seen before — cold, calculating, yet deeply human. You know she’s nailed her role when just one look or line delivery gives you chills. Jang Dong Yoon is equally impressive as the detective son, perfectly capturing a man torn between hatred for his mother and a buried longing for her approval. The supporting cast, including Lee El, Kim Bo Ra, and many others, round out the story with performances that make each episode feel rich and intense. Every hour flies by, making it feel like 1 hour is so short
Don’t forget, “Queen Mantis” is now streaming on KOCOWA+ with multiple subtitles available. Make sure to catch up before the finale and see for yourself who the real copycat killer is — because this ending promises to be unforgettable!
