Agent Kim Reactivated Achieves Record-Breaking Ratings
According to Nielsen Korea, Episode 4, which aired on July 4, recorded an impressive 21.6% nationwide rating, with peak viewership climbing as high as 25.1%. The drama has also maintained its position as the most-watched program in its Friday-Saturday time slot.
The series has enjoyed remarkable week-to-week growth since its premiere. It debuted with a solid 9.5% rating before climbing to 15.7% in Episode 2, 18.8% in Episode 3, and finally breaking through the 20% barrier with Episode 4.
In an era when Korean television dramas rarely achieve such high ratings, Agent Kim Reactivated has emerged as one of the industry's biggest success stories. It also ranks among SBS's highest-rated Friday-Saturday dramas, following only The Penthouse 2 and The Fiery Priest.
The drama is also attracting younger viewers, posting strong ratings among audiences aged 20 to 49, demonstrating its appeal across multiple generations.
Taecyeon's Surprise Appearance Changes Everything
One of Episode 4's biggest talking points was the highly anticipated appearance of 2PM's Taecyeon.
Taecyeon makes his debut as Park Young Gwang, a former elite agent who trained alongside Kim Do Hyun (So Ji Sub). His character's mysterious past is deeply connected to the protagonist, revealing painful memories that have haunted Kim Do Hyun long before he chose a quiet life as an ordinary father.
The arrival of Park Young Gwang not only expands the drama's emotional depth but also introduces new questions about the secretive "Agent 66" program, setting the stage for even more intense confrontations in upcoming episodes.
The Search for Min Ji Raises the Stakes
Beyond its explosive action scenes, Agent Kim Reactivated continues to resonate with viewers through its emotional father-daughter storyline.
Kim Do Hyun relentlessly risks everything to rescue his missing daughter, Min Ji, refusing medical treatment even after suffering injuries. The revelation that Min Ji is still alive gives both the protagonist and viewers renewed hope while significantly raising the emotional stakes.
This powerful combination of thrilling action and heartfelt family drama has become one of the series' greatest strengths.
Fans Predict Major Changes from the Original Webtoon
Another reason fans are eagerly discussing the series is its apparent departure from the original webtoon.
Sharp-eyed viewers noticed that certain details surrounding Min Ji's disappearance differ from the source material, leading many to speculate that the television adaptation may take the story in an entirely new direction. These changes have sparked lively discussions online as fans eagerly share theories about what could happen next.
Why Agent Kim Reactivated Is 2026's Must-Watch K-Drama
With So Ji Sub delivering one of his strongest performances in years, Taecyeon's scene-stealing debut adding fresh intrigue, and ratings continuing to climb at an extraordinary pace, Netflix's Agent Kim Reactivated has firmly established itself as one of the biggest K-dramas of 2026.
If the current momentum continues, the series could become one of the highest-rated Korean dramas of the year while cementing its place as one of Netflix's standout Korean releases.
