김부장 드라마, 방영 2주 만에 시청률 21.6%와 유튜브 리뷰 화제

So Ji-sub's SBS Friday-Saturday drama 'Kim Bujang' has been shaking both the living room and YouTube within two weeks of its premiere. Episode 4, aired on July 4, recorded a nationwide average rating of 21.6% (Nielsen Korea, peak 25.1%), clearing the elusive 20% mark. When each Friday and Saturday night broadcast ends, review-channel binge recaps and official clips push view counts up overnight in a repeating pattern. The way a broadcast hit spreads onto YouTube is another axis of this success.

From 9.5% in Episode 1 to 21.6% in Episode 4, Ratings Climbed Every Week

So Ji-sub's SBS Friday-Saturday drama 'Kim Bujang' cleared the elusive 20% mark in just four episodes, with a nationwide average rating of 21.6% (Nielsen Korea, peak 25.1%). Starting at 9.5% in Episode 1, it rose to 15.7% in Episode 2, 18.8% in Episode 3, and 21.6% in Episode 4, climbing every week and taking third place in the all-time ranking of SBS Friday-Saturday dramas nationwide. It sits behind The Penthouse 2 (29.2%) and The Fiery Priest (22%), and is the first drama in about two years, since 2024, to reach the 20% range.

The domestic hit spread to OTT as well. In Netflix's non-English category, it reached No. 3 globally as of July 5, 2026, and a consumption pattern took hold in which the Friday and Saturday broadcasts flow straight into streaming right after airing.

Gathering the key figures in one place makes the scale of the buzz clear.

The upward curve itself keeps generating fresh search demand as raw material.

Why It Worked: A 'Korean Taken' Mixing Fatherly Love and Espionage

The force that lifted ratings from 9.5% in Episode 1 to 21.6% in Episode 4 lies in a setup that layers fatherly love and espionage action onto a single character. 'Codename 66,' a special agent who operated on both sides of the North-South divide, has been hiding as an accounting-team manager at Sangsaeng Savings Bank; when his daughter Kim Min-ji (Seo Su-min) faces school violence and abduction, he declares himself a 'lawless middle-ager' and sets out to track them down. Viewers frequently call it a 'Korean Taken.'

The source is the webtoon 'Kim Bujang,' serialized on Naver since 2021, the fifth live-action adaptation from the 'Park Tae-jun Universe.' The high fidelity between webtoon and drama is cited as a reason original-webtoon fans came along, and the question 'how is it different from the webtoon' has become a staple of searches and reviews.

The casting also amplified the buzz. So Ji-sub's chemistry with Choi Dae-hoon (as Seong Han-su) and Yoon Kyung-ho (as Park Jin-cheol), joined by Joo Sang-wook, Son Na-eun, Ok Taec-yeon, and Kim Sung-kyu, gives each character a distinct color. The father-daughter chemistry created by Seo Su-min in the daughter role is the point that drew the fastest reaction right after airing.

The Scale of the Buzz Spreading onto YouTube

The broadcast buzz shows up on YouTube as sheer scale. Videos with 'Kim Bujang' in the title and over 100,000 views have posted 37 times since June 2026, and 13 channels gathered a combined 19.08 million views (Dhesy data, tallied from June 1 to July 5, 2026). It is the result of reviews, official clips, and variety shows all reacting to one drama at once.

The channel that gathered the most views is SBS Sbeuseu Drama, which posts official clips, with 3.98 million combined, followed by review channels Kim Si-seon (3.58 million) and Gomong (2.86 million). Down to Jeongssine (2.07 million) and Jamjam Review (1.88 million), the upper ranks are densely packed with review-type channels.

Laying the video counts and combined views of the top channels side by side, the presence of review-type channels is clear.

The point where channels in the 150K-subscriber range overlap in view scale with a 7-million channel is a signal that the binge-recap format absorbed the broadcast buzz directly.

How a Review Channel's Binge Recap Becomes an Entry Point for Watching

A single binge recap from a review channel serves as an entry point for new viewers. Kim Si-seon's 'Episodes 1-2 binge recap' single video recorded 3.58 million views, Gomong's summary review 2.41 million, and Jamjam Review's 'binge recap through the original webtoon's ending' 1.72 million. Viewers who missed the broadcast grasp the context through a summary and then move on to the live broadcast and Netflix.

The Shorts from these channels are mostly derivatives cut from the broadcast or from long-form reviews. In this tally there were 14 Shorts and 23 long-form videos, and Shorts are closer to a channel for spreading the broadcast original and long-form pieces in short bursts. The body that drove views is long reviews such as binge recaps and summaries, while Shorts take on the role of spreading that buzz widely.

A structure where cheering, analysis, and clips climb together on a single event is also observed in the World Cup YouTube case.

The Division of Roles Between Official Clips and Reviews

The 13 channels that filled the top ranks split into three shares. Official channels such as SBS Sbeuseu Drama, SBS Catch, and Netflix Korea post broadcasts, previews, and Shorts, while review channels handle summaries, interpretation, and binge recaps. Adding to this, variety clips such as Diggle's You Quiz on the Block appearance video bring the three layers together to lift one another.

The roles the three layers divide over the same drama can be organized as below.

Official clips cut and spread the broadcast moment, reviews fill in the context, and variety shows pick up the actors' buzz, a division of labor that runs at once inside a single drama.

Buzz Riding on the Broadcast: Will It Continue After the Finale?

The limit of this flow is that most of the YouTube response rides on the original event of broadcasting. This tally's 14 Shorts and 23 long-form videos are mostly derivatives of the broadcast original, so their independent staying power is limited, and how much review and binge-recap demand remains after the finale is still uncertain. If the fresh material of broadcasting runs out, the view growth of the top videos may also flatten.

Conversely, if Netflix, reruns, and YouTube binge recaps hold long-tail demand, the story changes. If 'Kim Bujang' carries the buzz along that path, the same spread formula, review and official clip channels attaching at once the moment a show airs, is likely to recur in the next hit live-action webtoon adaptation. This case, where even a mid-size review channel like MadMovie climbed into the top ranks, brings that possibility forward.
