A Record-Setting Start
According to Nielsen Korea, the first episode of Doctor X averaged a nationwide rating of 11.4 percent. That’s the highest premiere rating of any miniseries in 2026 so far. It also made the drama the most-watched show of any kind to air on Friday, which is a strong result in a competitive evening slot.
Double-digit numbers on a debut are hard to come by in today’s fragmented TV landscape. Premiere ratings don’t guarantee how a series will perform later, but a start like this gives the show valuable momentum and a lot of early word of mouth.
The Story: A Surgeon Who Operates on the System
The series is based on the hit Japanese drama of the same name, and Doctor X has a reputation for its fiercely skilled, independent heroine. In the Korean version, Kim Ji Won plays Gye Soo Jung, a genius surgeon who proves what it really means to be a doctor through pure skill alone. Her toughest patient isn’t a person on the operating table. It’s a corruption-ridden establishment, which she “operates” on just as precisely.
That premise gives the drama two engines: gripping surgical set pieces and a sharp, noir-flavoured story about power and corruption. It’s a combination that tends to keep viewers coming back each week.
Why Kim Ji Won Is the Draw?
Kim Ji Won has built a loyal following with roles that mix warmth with strength, and her work in Fight for My Way remains a favourite with fans. Casting her as a ruthless, brilliant surgeon is a bold shift, and the ratings suggest audiences are curious to see her take on the role. Fans who love her in lighter, romantic dramas may be pleasantly surprised by this edgier turn.
What to Watch For Next?
The big question now is whether Doctor X can hold or grow its audience across the coming weeks. If it does, it could become one of the standout hits of the year. For now, the cast and crew have plenty to celebrate.
