Sky Castle is currently the highest-rated Korean drama in cable television.[9] It was an unexpected commercial hit, rising from 1% viewership ratings to double-digit viewership ratings percentage; as well as topping the Contents Power Index (CPI) rankings as well as the TV popularity ranking in Korea.[27][28][29] Besides its popularity in South Korea, the series also gained immense popularity in China.[30]

Critical reception

The drama series has drawn positive reviews as a dark comedy that casts light on some of the furtive and controversial aspects of Korean society. It has also stimulated explosive responses from viewers due to its relatable storyline over Korea's competitive education system.[31] Culture critic Jung Duk-hyun says the drama has received attention from viewers, because it successfully strikes an uneasy chord while heightening societies curiosities over the lengths to which rich elite families obsess over education. He also says "In terms of education, the drama satisfies people's desire to peek into what those closed rich family circles do for their children. But at the same time, viewers feel uneasiness when watching their stories. Those two conflicting emotions, 'wanting to know but feeling uncomfortable' makes for some interesting chemistry in the minds of drama fans and puts it on the must-see drama list." [32][33][34] The drama is also popular in China, where similar conditions and vexations overlap with those of Korea's education system.[30][35]


The drama ignited a controversy for allegedly "inciting" the murder of psychiatrist Lim Se-won, as it aired a scene in which a patient chases after a doctor with a knife in his hand due to a grievance over his operation results.[36]

Following the broadcast of episode 14 on January 5, several Korean netizens on online communities came up with their own theories about what will happen next. One netizen’s theory was supported by what appeared to be a photo of the drama’s cue sheet, and another theory was formed based on the character description in a recruitment notice for a new role in the drama. When episode 15 aired on January 11, these theories proved to be true, making viewers question if the story was leaked.

On January 12, the producers explained that “the story was not leaked. Our viewers came up with many theories. They happened to be correct by chance, which must be why people think they are spoilers."[37]

On January 16, controversy rose again after a netizen uploaded photos of parts of the scripts for episode 17 and 18. The fact that the name “Cha Ki Joon” was left on the script drew much attention, and the photos began to spread on online communities.[38] After an investigation into the rumors, the producers of JTBC’s “SKY Castle” confirmed that the scripts for episodes 17 and 18 (to be aired on January 18 and 19) had been leaked.[39]

The production team was accused of plagiarizing the song "We All Lie" from American musician Bea Miller's song "To the Grave" featuring Mike Stud. However JTBC denied the accusations.[40]

The word SKY is an acronym used to refer to the three most prestigious universities in South Korea: Seoul National University, Korea University, and Yonsei University.[6][49] The term is widely used in South Korea, both in media broadcast and by the universities themselves.[50][51]

In South Korea, admission to one of the SKY universities is widely considered as determining one's career and social status.[52][49] Many of South Korea's most influential politicians, lawyers, physicians, engineers, journalists, professors, and policymakers (bureaucrats) have graduated from one of the SKY universities.
