Audience Opinions

Audience 8.1/10
"A grim, slow-burning profiler drama defined by phenomenal acting and uncompromising psychological depth."

Performances, especially Kim Nam-gil and the actors portraying serial killers, are repeatedly singled out as gripping, nuanced, and emotionally devastating, backed by tight writing that prioritizes grief, victims, and the birth of criminal profiling over flashy twists. The heavy, talk‑driven structure and lack of romance create a uniquely intense atmosphere that many find top-tier for the genre, while others struggle with the slow pace, dragging later episodes, and the limited impact of the female characters.

What viewers praise
  • Standout lead performance Kim Nam-gil’s subdued, deteriorating profiler is praised as one of his best roles, conveying empathy, exhaustion, and psychological collapse with remarkable restraint.
  • Terrifying killer portrayals Actors playing the murderers are widely described as phenomenal, adding a chilling realism that makes interrogations and confessions unforgettable.
  • Victim-focused writing The story keeps attention on grief, the bereaved, and the ethical side of profiling instead of glorifying or humanizing the criminals.
  • Serious psychological depth The show leans into whydunnit profiling, in-depth interviews, and the birth of a behavioral unit, drawing frequent comparisons to prestige psychological crime dramas.
  • Strong overall craft Cinematography, music, and direction are consistently described as professional, atmospheric, and worthy of a high-end crime series.
Common complaints
  • Very slow pacing The dialogue‑heavy investigations and methodical structure feel too slow or even boring for those expecting a more conventional thriller tempo.
  • Emotionally exhausting tone Its relentless focus on serial killings, victim grief, and profiler burnout, with no romance or comic relief, can feel overwhelmingly bleak.
  • Uneven final stretch Several viewers note that the excitement and tension dip in the later episodes, making the closing arc feel dragged out compared to the early cases.
  • Underused female characters The prominent women, particularly the reporter, are criticized for not influencing the plot much despite the premise promising strong female roles.
  • Less grounded than expected For some, the dramatized, slightly sensational approach and coincidences feel less realistic than comparable profiler dramas, weakening its impact.

“Through the Darkness,” No Scandals in Sight: The Eerily Clean Gossip File On K-Drama’s Grim Masterpiece

If you came here hoping Through the Darkness had secret love triangles, screaming matches in the makeup trailer, and a director storming off set… you’re about to discover something even rarer in dramaland: a hit show where the mess is all on-screen and almost never off it. Let’s dig into the surprisingly wholesome “tea” around this terrifyingly good thriller.


Cast Feuds & On-Set Drama (Or Lack Thereof…)

  • Fans on Reddit rave about the show’s chemistry and execution, calling it “arguably the best crime kdrama in existence,” with “top-notch” acting across the board — and absolutely zero whispers of cast infighting behind the scenes .
  • Discussion threads focus heavily on how well everyone fits their roles and how cohesive the ensemble feels, not on who allegedly couldn’t stand whom between takes [1][2].
  • If there was drama, it never bubbled up to fan forums, Soompi articles, or gossip socials. For a show this intense, the biggest fight seems to have been with viewers’ sleep schedules.

Romance Rumors: Ghosted By Scandal

  • Kim Nam Gil has had his fair share of romance buzz in the past — from alleged chemistry-driven rumors with Son Ye Jin during Shark, which both denied , to long-standing fan curiosity about his love life — but none of that heat attached itself to Through the Darkness.
  • During promos, coverage of Kim Nam Gil focused on his craft and how he took on the real-life-based profiler role as a serious acting challenge, not as a route to couple-brand headlines .
  • Co-stars Jin Seon Kyu and Kim So Jin? Squeaky clean in the rumor department. No dating/breakup chatter, no “caught leaving the same van” discourse, just “wow, they’re amazing actors” energy [4].
  • So yes: for this drama, all the obsession stayed strictly fictional and murder-y.

Bromance, Not Romance: The Kim Nam Gil × Jin Seon Kyu Effect

  • Fans are absolutely feral for the Ha-young/Young-soo partnership. One Reddit review flat-out credits the “heart-melting chemistry” between Kim Nam Gil and Jin Seon Kyu as a major draw of the series [1].
  • A K-drama blogger gushed about their “onscreen bromance,” clearly rooting for more projects with the two together .
  • Social posts and TikTok edits lean into their dynamic as the emotional spine of the show — a stoic profiler and his dogged team leader partner, bonding over serial killers and bureaucracy instead of flowers and chocolates [1][6].
  • Unconfirmed but widely assumed by fans: the warmth and ease they show in interviews and press events strongly suggest a genuine off-screen camaraderie, even if neither actor has turned it into a public bro-romance narrative.

Scandals & Controversies: The Drama Is Elsewhere

  • Reviewers call Through the Darkness a “slow treat” with “realistic” villains and thoughtful storytelling, not a shock-value gorefest [5]. That tone extended off screen: no production lawsuits, no labor complaints, no “problematic content” boycotts surfaced in the usual drama circles.
  • Reddit drama threads about the show’s “controversies” are more about taste than scandal — some viewers complain it’s too slow or too heavy on profiling talk, especially compared to flashier thrillers [2]. That’s as spicy as it gets.
  • The only real swirl of controversy connected to Kim Nam Gil in recent years is outside this drama: his very public decision to turn down Netflix’s Teach You a Lesson, a corporal-punishment-themed project that drew heavy backlash, led to a separate casting storm and industry debate . Fans of Through the Darkness often cite this as further proof he gravitates toward morally serious material — but that’s meta, not messy.

Wild Trivia & Behind-the-Scenes Nuggets

  • The characters of Kim Nam Gil and Jin Seon Kyu are explicitly modeled on real people: Prof. Kwon Il-yong, Korea’s first criminal profiler, and police officer Yoon Oe-chul [5]. This wasn’t just “inspired by true events” marketing — the drama presentation spelled it out.
  • At a pre-broadcast event, production staff explained they were adapting a non-fiction book and wanted to show psychological analysis as a legitimate tool of investigation, not just TV magic [5]. That commitment to realism is a recurring talking point in reviews [7].
  • Kim Nam Gil described the role as a big shift away from his usual brighter or more comic characters, saying he wanted to dig into a colder, more restrained persona with deep empathy underneath [4][5]. Fans and critics later pointed to this as a key reason his SBS Grand Prize win felt inevitable.
  • Kim So Jin leaned into portraying a female detective facing 1990s-era prejudice, emphasizing her character’s “solid charisma” and frustration in a male-dominated field [5] — an angle reviewers praised for adding social bite to the procedural.

Fan Reactions & Mini Theories

  • Long Reddit breakdowns debate whether the show is Korea’s answer to Mindhunter — some adore the cerebral approach, others complain that “all they’re trynna do… is ‘analyze’ culprits” and wish for more conventional thriller pacing [2][8].
  • Rather than wild plot conspiracies, most fan discourse is about the emotional toll on Song Ha Young: viewers parse his micro-expressions, his quiet breakdowns, and his childhood trauma, building headcanon about how close he is to snapping. It’s speculation, not scoop — but it shows how deeply the character got under people’s skin [1][2].

In the end, Through the Darkness might be the rare K-drama where the juiciest story is the one you watched: no leaked scripts, no secret lovers, no van-cam fights — just a tight cast, a haunted profiler, and a series so clean behind the scenes it almost feels… suspicious.
