You could say Netflix has an obsession with this one. The numbers don’t lie – a 15.7 percent nationwide rating for Agent Kim Reactivated is the swiftest anyone has seen a show get over the 15 percent line since The Penthouse 3, and that was half a decade back. It is also the best thing to come out of SBS this year.
Why it is dominating conversations right now
The first couple of episodes were more than just a soft opening; they were a run-up. After the premiere set a mark for 2026 miniseries, the second one lured in even more people to make it the week’s top program. You don’t see that kind of week-to-week jump often, but fans and the talking heads are calling it what it is: a breakout.
Then again, it is not only about the figures. There is something to be said for the story’s simple pull: a soft-spoken, single father who has to let some old demons out when his teen daughter is gone. What you get is an action-thriller with a bit of a rough edge and a lot of heart.
So Ji Sub’s action return has the fandom buzzing
It is hard to forget where he has been. From Sorry, I Love You (2004) to Cain and Abel (2009) and Always (2011), So Ji Sub has made his mark. He had us in his grip with The Master’s Sun and Oh My Venus, and then showed off some film chops in A Company Man and The Battleship Island.
Now in 2026, he is back on the small screen with a story of retribution that is as much about feeling as it is about force. People are making note of how well he can be a broken-up father and a no-nonsense fighter in the same scene and still be the same guy.
What the story promises
Some will tell you this is based on Toy’s webtoon Manager Kim. In that version, you have So Ji Sub as Kim Do-Hyeon, or Codename 66, an ex-North Korean spy who was minding his own business at a bank until his daughter Min-Ji was taken and his quiet life was over.
He has to put on the old hat and go after her, which means running into some old faces from the Special Mission Bureau like Seong Han-Soo and the “God of War” Park Jin-Cheol. On the other side of the table is Ju Gang-Chan, a construction boss with a lot of power and not an ounce of conscience.
But it is the father’s word that drives it. That makes every scuffle and foot chase mean something, so the violence doesn’t just look good for the camera.
Another way to put it
If you read a different synopsis, you might find So Ji Sub is Kim Seok Joo, an NIS man who bailed after a mission went sideways and is being called back in. This one puts in Seo Yoon Ji, Cha Min Ho, Kang Tae Sik and Kim Ha Neul as Director Hwang, along with Lee Joon Hyuk, Jang Hyuk and Lee Young Ae.
Behind the scenes on that front are the likes of Lee Yoon Jung (The Veil, Vagabond) and scribes Jang Young-chul and Jung Kyung-soon, who have their fingers in pies like The Penthouse and The Vengeance Trilogy.
The numbers, unchanged and impossible to ignore
Put simply, here is what the ratings are saying:
– No drama has hit 15 percent in its stride like this one has since 2021
– We are at 15.7 percent by the time you finish episode two
– It is the top of the heap for SBS in 2026
All in, the series on both SBS and Netflix is shaping up to be a major hit. And the fact that it is picking up steam, not losing it, is the true measure of a show that can hold your attention.
Cast line-up and where to watch
Aside from So Ji Sub, you have Choi Dae-Hoon as Sung Han-Soo, Yoon Kyung-Ho as Park Jin-Cheol and Joo Sang-Uk as Joo Kang-Chan. Son Na-Eun is there as Jung Sang-A, with Seo Su-Min as Kim Min-Ji and Yu Ji-Ahn as Joo Hye-Ri.
You can stream it on Netflix, so it is as easy as can be to follow along. The way the show is going, with its mix of high-stakes and heart, the word on the street is only going to grow.
