The action-packed series 'Agent Kim Reactivated' has made a remarkable comeback, with its viewership skyrocketing from 9.5% in its premiere episode to an impressive 20% by the fourth episode. This series marks the return of popular actor So Ji Sub, who plays the lead role. According to reports from The Korea Times, the show has climbed to the top of Netflix's rankings for non-English language films, ending a four-week reign of the series 'Teach You a Lesson'. In just one week, 'Agent Kim Reactivated' attracted 10.5 million views, establishing itself as a leading program across various countries.

In South Korea, the show has also achieved significant ratings success. Nielsen Korea reported that the fourth episode aired on SBS garnered a national rating of 21.6%, making it the third highest-rated drama in SBS history for the Friday-Saturday time slot, following 'The Penthouse 2' and 'The Fiery Priest'. The ratings have consistently increased since the show's debut, with figures rising to 15.7%, 18.8%, and surpassing 20% in the fourth episode.

'Agent Kim Reactivated' tells the story of Kim Do Hyeon, portrayed by So Ji Sub, a former agent who now works at a small bank, trying to lead a quiet life in accordance with his deceased wife's wishes. Initially depicted as a mild-mannered middle-aged man focused on his only daughter, Min Ji, Kim's life takes a dramatic turn when Min Ji stands up to her bully, Joo Hye Ri. The situation escalates, leading to Min Ji's disappearance, which forces Kim to awaken his buried combat skills to rescue her. The narrative explores themes of parental protection and the emotional turmoil of a father willing to do anything for his child.

The show has been praised for its depth, moving beyond a simple revenge tale to explore the characters' motivations and relationships. The emotional performances, particularly by So Ji Sub, have resonated with audiences, contributing to the show's popularity. The producers noted that the theme of a father fighting to protect his family has struck a chord with viewers across generations.

'Agent Kim Reactivated' is adapted from the webtoon 'Manager Kim' by Park Tae Jun. While it retains much of the original storyline, the series introduces characters earlier and provides insights into their daily lives before the main plot unfolds. This approach adds depth to the narrative, allowing for a richer viewing experience.

As the series continues to gain traction on Netflix, it has quickly risen to the top 10 of non-English language television shows globally within just three days of its release. The show's success can be attributed to its direct storytelling style and its exploration of justice outside the confines of the legal system, resonating with viewers who seek a sense of retribution through Kim's actions.

So Ji Sub's portrayal of Kim, along with the supporting performances from Choi Dae Hoon and Yoon Kyung Ho, balances tension with moments of humor, creating a compelling camaraderie that enhances the overall narrative. 'Agent Kim Reactivated' not only delivers thrilling action but also addresses pressing social issues, critiquing the disparities between the working class and the elite, and reflecting the frustrations of viewers who feel powerless in today's society.
