Revenge has never been more popular in K-dramas. From brutal action sequences to emotionally charged stories of justice, two of 2026's biggest Korean dramas—SBS's Agent Kim Reactivated and Netflix's Teach You a Lesson—are dominating both television ratings and global streaming charts.
But their success has also raised an important question:
Why are audiences so drawn to violent, revenge-driven stories?
Agent Kim Reactivated Becomes One of SBS's Biggest Hits
Starring So Ji-sub, Agent Kim Reactivated follows the story of a devoted father who launches a relentless search for his missing daughter, stopping at nothing to uncover the truth.
The drama has become one of the biggest television successes of the year. Episode 8 achieved an impressive 23.1% nationwide viewership rating, making it the second highest-rated SBS Friday-Saturday drama of all time, behind only The Penthouse 2.
Viewers have praised the series for its gripping suspense, emotional storytelling, and So Ji-sub's powerful performance. However, its graphic fight scenes and intense revenge sequences have also become a major topic of discussion.
Netflix's Teach You a Lesson Finds Global Success
Another surprise hit is Netflix's Teach You a Lesson.
The drama follows members of a fictional Ministry of Education task force tasked with protecting teachers' authority. Instead of solving problems through traditional methods, its protagonists often confront violence with even greater force.
The series quickly attracted international attention and ranked among Netflix's most-watched titles worldwide during the first half of 2026.
While many viewers applaud its fast-paced storytelling and satisfying moments of justice, critics argue that the show blurs the line between discipline and excessive violence.
Why Are These Stories So Popular?
The growing popularity of these dramas has sparked debate among psychologists and media experts.
Some mental health professionals point to recent psychological research suggesting that people experiencing stress, frustration, or negative emotions may naturally gravitate toward darker or more emotionally intense content.
According to a 2025 study conducted by researchers from Stanford University, MIT, and University College London, participants who were feeling emotionally worse before browsing the internet were more likely to consume negative or disturbing content. Likewise, people who regularly consumed more negative content often reported poorer mental well-being.
While researchers caution that the relationship is still being studied, the findings suggest that emotional state and media choices may influence one another.
Or Is Revenge Simply Timeless Entertainment?
Not everyone agrees that the popularity of these dramas reflects society's emotional state.
Media scholars argue that stories about revenge, justice, and overcoming corruption have captivated audiences for centuries.
From classic literature and folklore to modern films and television, people have always enjoyed narratives where ordinary individuals confront powerful villains and ultimately restore justice.
In today's streaming era, viewers also have greater freedom than ever before to choose the stories they genuinely enjoy, making it difficult to attribute the success of revenge dramas to any single social trend.
More Than Violence—A Search for Justice
Perhaps what makes these dramas resonate isn't the violence itself.
Both Agent Kim Reactivated and Teach You a Lesson center on characters fighting against systems that appear broken or unjust. Their emotional appeal often comes from watching determined protagonists stand up for victims when institutions fail to deliver justice.
For many viewers, these stories provide a sense of catharsis—a chance to witness wrongs being righted, even if only on screen.
Final Thoughts
Whether their popularity reflects today's social frustrations or simply continues one of storytelling's oldest traditions, one thing is clear:
Revenge-driven K-dramas are among the defining entertainment trends of 2026.
As audiences continue to embrace emotionally intense stories filled with suspense, action, and moral dilemmas, dramas like Agent Kim Reactivated and Teach You a Lesson are proving that viewers aren't just looking for violence—they're searching for compelling stories where justice, in one form or another, ultimately prevails.
