A new dark K-drama is coming to Netflix, and it's already promising to hit hard. "Mercy for Nonewith So Ji-Sub and Lee Jun-Hyuk (Love Scout) in the lead, blends vengeance, family secrets and power struggles in a dark, unforgiving universe. Here's why this series, available since June 6, deserves a place at the top of your list.

A plot full of tension and secrets
Inspired by a cult webtoon, "Mercy for None follows in the tradition of the Korean noir thriller. But beyond the classic revenge plot, the series is distinguished by its nuanced writing. Each character has his or her own wounds, ambitions or moral dilemmas, making relationships complex and unpredictable. Episodes move forward with a masterful sense of suspense, distilling revelations in dribs and drabs and maintaining constant tension.
A five-star cast that commands respect
So Ji-Sub's return to a dark role was eagerly awaited, and he doesn't disappoint. He plays Nam Ki-Juna former gangster with a violent past, who has returned to the world he left behind to avenge his brother's death. His performance is all restraint and tension, at once chilling and deeply moving. Opposite him, Lee Jun-Hyuk (Love Scout), in the role of the missing brother, leaves a lasting impression despite limited screen time. Around them, a gallery of powerful characters: Heo Joon-Ho (seen earlier this year in the excellent Buried Hearts), Cha Seung-Won (The tyrant), Ahn Kil-Kang or even Jo Han-Chul (Vincenzo, The Creature from Kyŏngsŏng)... each brings his own intensity to the plot.

Nervous staging and incredible action scenes
No flashy special effects here, just hand-to-hand combat, brutal confrontations and chases in dark, confined spaces. The series adopts a raw, almost cinematic aesthetic, where every scene seems to weigh heavy with meaning and pain. So Ji-Sub impresses with his physical and emotional commitment, delivering a performance marked by restrained rage and desperate determination.
