The situation
SBS's "Agent Kim Reactivated" starring So Ji Sub premiered with the highest ratings of any miniseries in 2026, achieving a 9.5 percent average nationwide rating. This places it firmly in first place in its time slot across all channels. The strong start suggests a promising run for the action revenge drama.
What the internet did with it
- Netizens on Theqoo noted the high production value and So Ji Sub's performance, with one comment saying — "he's still got it, the action scenes were insane"
- MBC's "Fifties Professionals" also saw a significant bump in ratings, achieving its highest viewership yet with a 6.0 percent average nationwide rating ahead of its series finale
- The room on Instiz was relatively unbothered by the ratings competition, focusing more on the plot developments in both dramas
The open question
The key question now is whether "Agent Kim Reactivated" can maintain its high ratings throughout its run, especially with "Fifties Professionals" concluding soon and potentially freeing up viewers to switch to other shows. The upcoming episodes will be crucial in determining the drama's overall performance.
