‘Agent Kim Reactivated’ Sparks Fierce Debate With Its Fully AI-Generated Action Scene

‘Agent Kim Reactivated‘ has become one of the biggest talking points of the summer, not just for its ratings but for a bold creative choice that has split viewers down the middle. The SBS drama, which follows a former secret agent forced back into action to save his kidnapped daughter, decided to bring a major flashback sequence to life using artificial intelligence instead of traditional filming.

That decision has now snowballed into one of the most discussed pieces of Korean television news this year, with fans, critics, and industry watchers all weighing in on what it means for the future of the medium. The series stars So Ji-sub in the titular role alongside Choi Dae-hoon, Yoon Kyung-ho, Joo Sang-wook, Son Na-eun, and Kim Sung-kyu, and it is based on the Naver webtoon Manager Kim by Jeong Jong-taek and Toy.

The AI-Generated Action Sequence Explained

The scene in question arrives in the show’s early episodes and depicts the protagonist’s dangerous past. The roughly three minute sequence depicts the past of Manager Kim, played by So Ji-sub, and was produced entirely with AI, making it a rare example of a Korean drama using a single AI generated sequence to tell such an extended narrative. Set in North Korea, it follows Manager Kim as he carries out a special mission and was featured across the drama’s first and second episodes.

The visuals go far beyond a simple digital touch up. The AI generated footage includes large scale action scenes such as building explosions, high speed car chases on snow covered roads and through tunnels, vehicle rollovers and crashes, underwater submersion and vehicle recovery operations.

On a snowy night, a motorcycle pursues a black sedan into a mountain tunnel, a wire trap overturns the lead escort vehicle, and a masked man in a North Korean military uniform approaches the sedan before a gunfight and hand to hand combat follow.

What makes the sequence especially notable is how the studio handled character work. Aside from So Ji-sub, all other figures in the sequence are synthetic characters created by AI, with the scene even including close ups while keeping their appearances visually consistent. The sequence also depicts gunfights and hand to hand combat with close up shots of characters, addressing one of the major limitations of AI generated video by maintaining a high level of character consistency.

Why the Technology Behind the Scene Matters

The production company behind the sequence has been vocal about why this moment felt like a milestone rather than a shortcut. Morpheus Studio emphasized that the sequence was completed entirely using AICRON, a domestically developed AI platform, and said it was meaningful that the entire sequence was produced using Korean developed technology alone.

The studio has also pushed back on the idea that this was a cost cutting gimmick. A studio representative named Ryu said the biggest significance is that they did not simply replace a few seconds of visual effects with AI, but instead completed an entire story sequence essential to the narrative using AI, adding that Manager Kim was conceived from the planning stage with a clear purpose for incorporating the technology.

Getting the sequence to feel cinematic rather than artificial was reportedly the hardest part of the process. Ryu explained that no matter how realistic the images look, viewers notice when the flow feels wrong, so the team approached it as if they were shooting live action, paying particular attention to constructing and directing each shot using the visual grammar of cinema. The primary goal was to ensure the sequence did not look AI generated, and the main challenge involved action scenes with physical interaction between characters.

Fan Reactions to the AI Controversy Are Split

Online, the response has been anything but unanimous, and that tension is exactly what has kept the conversation alive. One viral TikTok from the Daebak K-Rambles Podcast account described having a crashout over the AI in ‘Agent Kim Reactivated’, while another creator questioned whether the colors, voices, and backgrounds felt so off and insincere that it amounted to AI slop, asking if other viewers had noticed the same thing. A separate clip from creator bad.korean.teacher summed up the general vibe with a simple description of having mixed feelings about the drama including a three minute AI scene.

Despite the online skepticism, the numbers tell a very different story domestically. Since premiering on June 26, the drama topped viewership charts, with episode six recording a nationwide rating of 22.3 percent and 23.2 percent in the Seoul metropolitan area.

Rather than turning viewers away, the AI sequence became another talking point for the series, which continued to dominate television ratings even as the reception in South Korea proved markedly different from the criticism seen around AI visuals in other countries.

The AI scene was not the show’s only source of viewer frustration either. The drama also drew criticism for what some viewers saw as an overload of product placement toward the end of the series, including scenes involving caffeinated candy and a conveyor belt sushi restaurant, with some complaining the placements were so obvious they pulled them out of the story. SBS later clarified that a widely discussed eyeglasses store scene in the finale was not actually sponsored, with a representative explaining it was included to symbolize the characters making a fresh start with new glasses rather than serving as an advertisement.

What This Means for the Future of K-Dramas

Even with the noise around both the AI sequence and the product placement chatter, ‘Agent Kim Reactivated’ closed out its run on an undeniable high. According to Nielsen Korea, the finale scored 23.4 percent in the Seoul metropolitan area and 23.0 percent nationwide, with a peak real time rating of 27.1 percent. That kind of finish suggests the AI experiment did little to dent the show’s mainstream appeal, even if it left a chunk of the internet unsettled.

Whether this becomes the norm or a one off experiment likely depends on how other studios read the response. For now, ‘Agent Kim Reactivated’ has proven that a fully synthetic action sequence can headline a ratings hit, even while a vocal slice of its audience insists the technology still has a long way to go before it feels indistinguishable from the real thing.

So now that the full picture is out there, do you think that three minute AI sequence in ‘Agent Kim Reactivated’ actually strengthened Manager Kim’s backstory, or did it pull you out of the story the second you noticed something felt off?
