Premise
The Good Detective is a South Korean crime thriller series that centers on the partnership between two contrasting detectives at the Seobu Police Station in Incheon, as they navigate complex investigations into concealed crimes and institutional corruption.[5] Veteran detective Kang Do-chang, with 18 years of experience, relies on intuition, street smarts, and personal connections forged over time, including with past criminals he has apprehended.[6] In contrast, experienced detective Oh Ji-hyuk, a graduate of the Korean National Police University, adheres strictly to legal procedures, evidence-based methods, and an exceptional memory for details, embodying a by-the-book approach to law enforcement.[6] Their unlikely collaboration, often joined by investigative reporter Jin Seo-kyung who aids in exposing hidden truths, forms the narrative core, highlighting the tension between instinct-driven policing and procedural rigor.[7] Set against the gritty urban backdrop of Incheon, South Korea, the series draws from real-world challenges faced by detectives, including bureaucratic obstacles, powerful interests seeking to bury scandals, and the ethical tightrope of pursuing justice in a flawed system.[3] It portrays the daily realities of frontline policing, where cases involve not just solving crimes but confronting cover-ups by those in authority, forcing characters to grapple with moral dilemmas about bending rules for the greater good.[5] Thematically, The Good Detective explores what constitutes a "good" detective in an imperfect world, pitting the drive to uncover truths against efforts to suppress them, while examining the personal costs of dedication to justice.[7] Across its two seasons, the narrative arc maintains this focus on investigative partnerships and systemic issues without resolving all conflicts, emphasizing ongoing battles between exposure and concealment in modern Korean society.[4]Format and production details

Season 1
Season 1 of The Good Detective centers on an investigation into a recent murder that uncovers links to a five-year-old cold case, revealing layers of evidence tampering, corporate influence, and internal police conflicts within the Incheon police force. The story follows veteran detective Kang Do-chang, portrayed by Son Hyun-joo, who partners with the principled newcomer Oh Ji-hyuk to probe the reopened murder of Yoon Ji-sun, a young woman whose case led to the conviction of an innocent man. Their collaboration begins amid skepticism and clashing methods—Do-chang relying on street smarts and networks, while Ji-hyuk adheres strictly to procedure—but evolves into a tense alliance as they navigate bureaucratic obstacles and threats from powerful interests tied to a chaebol family.[13] Key events unfold as the detectives discover manipulated evidence, including falsified alibis and suppressed witness testimonies, pointing to a serial killer operating under corporate protection. The partnership is tested by revelations of police complicity in covering up the original crime to shield influential figures, forcing Do-chang and Ji-hyuk to conduct covert inquiries outside official channels. Meanwhile, reporter Jin Seo-kyung emerges as a crucial ally, using her journalistic resources to corroborate leads and expose media biases that favor the elite, adding depth to the probe's external pressures.[5] Character developments highlight Do-chang's personal stakes, including his strained family dynamics with his sister and nephew, which underscore his unorthodox approach to justice as a means of providing for them amid financial hardships. Ji-hyuk grapples with ethical dilemmas tied to his elite background, while Jin Seo-kyung's determination stems from her own past encounters with institutional failures. These arcs humanize the investigators, illustrating how personal motivations intersect with professional duties in a corrupt system.[4] The season builds to a climax where arrests expose higher-level cover-ups involving corporate executives and complicit officials, delivering partial resolution to the cold case while hinting at broader systemic issues in law enforcement and business. This conclusion reinforces themes of truth versus power, setting a foundation for ongoing struggles against institutional rot without fully eradicating it.[13]Season 2
The second season of The Good Detective, which premiered on JTBC on July 30, 2022, and concluded on September 18, 2022, centers on a new high-profile investigation into an assault case that spirals into a serial murder probe tied to corporate scandals within the influential TJ Group conglomerate. Building briefly on the unresolved family dynamics from the first season, such as Kang Do-chang's role as guardian to Eun-hye, the narrative escalates the detectives' pursuit of truth amid escalating dangers in Incheon. The season explores the clash between persistent investigators and powerful entities attempting to bury evidence, highlighting systemic corruption in both corporate and law enforcement spheres.[14][3][15] Key events unfold as Detective Oh Ji-hyuk, now transferred and promoted to partner with Kang Do-chang in the West Incheon Police Violent Crimes Unit 2, reopens the case of a brutal beating at a Gangnam host club involving victim Kim Min-ji and suspect Cheon Sang-woo, the vice-president of TJ Group. This investigation intersects with a chilling serial killer case handled by Kang Do-chang's team, where female victims are found dressed in white, including TJ Group legal employee Jung Hee-joo as a targeted individual. New antagonists from the TJ Group, such as the cunning Cheon Na-na and executive Woo Tae-ho, intensify the conflict, while revelations of deeper police corruption—stemming from internal pressures and external influences—complicate the detectives' efforts and introduce betrayals within the force. The core team, including supporting officers, faces mounting obstacles as the cases reveal a web of cover-ups linked to the conglomerate's operations.[11][12][16] Character developments emphasize Oh Ji-hyuk's growth following his promotion, as he integrates his evidence-driven approach with Kang Do-chang's intuitive style, fostering a stronger partnership and personal resilience amid professional rivalries resolved from prior tensions. Supporting character Song Ji-ho, the rookie detective, assumes an expanded role, taking on more investigative responsibilities and demonstrating increased confidence in high-stakes scenarios. The season introduces new allies, such as forensic experts aiding the team, and formidable foes from TJ Group's inner circle, which heightens interpersonal dynamics and underscores themes of loyalty and moral compromise within the police unit.[17][18][19] The resolution unravels a broader conspiracy orchestrated by TJ Group influences extending to regulatory agencies in Seoul, culminating in the detectives' dogged pursuit of justice against overwhelming power structures. Through collaborative efforts, the team exposes key perpetrators, delivering closure to the serial murders and assault while reinforcing the series' exploration of ethical dilemmas in upholding the law. This arc amplifies the season's focus on the triumph of integrity over corruption, with lingering personal stakes adding emotional weight to the victories achieved.[20][14][21]Cast

Development and writing
The series The Good Detective originated as an original screenplay penned by Choi Jin-won, who crafted a narrative centered on the gritty realities of police investigations in Incheon, South Korea. Produced by Blossom Story, SLL, and Drama House, the project was developed by JTBC in collaboration with writer Choi and director Jo Nam-gook, marking a reunion for the creative team following their prior works together. Pre-production began in late 2019, with the drama positioned as a realistic crime thriller that delves into ethical complexities and flawed investigative processes rather than relying on conventional genre tropes like infallible heroes or simplistic resolutions.[7] The writing process emphasized character-driven storytelling, contrasting veteran intuition with modern evidentiary methods to highlight systemic challenges in law enforcement, while steering clear of melodramatic clichés through nuanced portrayals of corruption and personal motivations. This approach was informed by the director and writer's intent to ground the series in authentic detective dynamics, avoiding exaggerated action sequences in favor of procedural depth and moral ambiguity. Initial announcements in 2019 outlined the drama's focus on uncovering hidden truths amid institutional obstacles, with an original premiere slated for April 2020 before being postponed to July due to the COVID-19 pandemic.[5] Following the success of the first season, which achieved peak viewership ratings above 5% and garnered praise for its compelling script, JTBC greenlit a second season in April 2021 to continue the storyline. The decision to split the series into two seasons stemmed from the original's popularity, allowing the writing team to expand on unresolved themes without rushing the narrative, with production resuming under the same creative leadership.[25]Casting
The casting process for The Good Detective commenced in early 2020, with the lead roles announced simultaneously by JTBC on January 13. Son Hyun-joo was selected to portray the veteran detective Kang Do-chang, a role that highlighted his experience in gritty character-driven narratives following a break from television. Jang Seung-jo was cast as the principled yet conflicted Oh Ji-hyuk, bringing his background in intense thrillers to the part, while Lee Elijah joined as the tenacious reporter Jin Seo-kyung, adding depth to the investigative dynamic with her rising prominence in supporting roles.[26] Supporting cast announcements followed shortly thereafter, with Oh Jung-se confirmed on January 22 to play the morally ambiguous chaebol heir Oh Jong-tae, a key antagonist whose layered portrayal drew on the actor's versatility in villainous characters. Additional ensemble members, including Ji Seung-hyun as the rookie detective Yoo Jung-suk and Kim Ji-hoon as the detective Byun Ji-woong, were integrated to bolster the procedural realism of the police unit.[27] For the second season, production confirmed in April 2021 that Son Hyun-joo and Jang Seung-jo would reprise their lead roles as Kang Do-chang and Oh Ji-hyuk, ensuring continuity in the core detective partnership.[28] Lee Elijah did not return, with her character omitted from the narrative, marking a notable shift in the ensemble. Oh Jung-se made a guest appearance as his season 1 character in episode 8. New additions were announced on June 29, 2022, including Kim Hyo-jin as the director of TJ Group Cheon Na-na and Jung Moon-sung as her affluent husband, enhancing the season's focus on corruption and elite influences.[29] No major recasts occurred among the principal returning actors, though the expanded supporting lineup introduced fresh dynamics without disrupting the established tone.Filming and challenges
Principal photography for The Good Detective took place primarily in Incheon, South Korea, to reflect the series' setting and provide an authentic portrayal of urban police work, with key scenes filmed at actual police stations and city locales.[30] The production of Season 1 faced significant hurdles due to the COVID-19 pandemic, which delayed filming and shifted the premiere from its original April 2020 slot to July 6, 2020.[31] Season 2 encountered further challenges when lead actor Son Hyun-joo tested positive for COVID-19 on February 27, 2022, prompting a temporary halt to filming as he underwent home treatment following guidance from health authorities.[32] Production resumed after his recovery, with JTBC confirming no anticipated impact on the overall schedule.[32] Filming for Season 2 concluded in May 2022, enabling post-production to proceed ahead of its July premiere.[33]Music

The original soundtrack (OST) for the second season of The Good Detective was composed primarily by Park Se-joon, who served as the music director to create a tense, atmospheric score that complements the series' crime drama elements.

On IMDb, the series holds an average rating of 7.6 out of 10 based on 1,787 user votes, with reviewers highlighting its strong direction, scripting, and acting that build tension between protagonists and antagonists.[3] Similarly, on MyDramaList, Season 1 averages 8.3 out of 10 from over 9,400 users, while Season 2 scores 8.2 out of 10 from more than 3,600 users, reflecting broad appreciation for the ensemble performances and character dynamics.[1][2] Critics have lauded the series for its realistic portrayal of policing, emphasizing ethical challenges and the pursuit of truth over procedural perfection. A Forbes review commended the show for questioning what defines a "good detective," particularly through its suspenseful plot involving flawed investigations and potential miscarriages of justice, with strong performances by lead actors Son Hyun-joo as the seasoned detective Kang Do-chang and Jang Seung-jo as the idealistic Oh Ji-hyuk.[7] Dramabeans echoed this, praising Son Hyun-joo's charismatic yet bumbling portrayal and the duo's chemistry as a fresh subversion of the buddy cop trope, infusing humor and insightful commentary on systemic biases in law enforcement.[5] The script's tension in investigations and team camaraderie were frequently noted as strengths, contributing to an emotionally resonant narrative that balances crime-solving with personal growth.[52] While Season 1 was often celebrated for its thought-provoking take on corruption and detective partnerships, Season 2 drew some mixed feedback regarding pacing and resolution.
