'Notes from the Last Row' review: Where does artistic license end?

This review contains some spoilers for the Netflix series "Notes from the Last Row."

Heo Mun-o (Choi Min-sik) is a pompous, aging Korean literature professor who has spent years burying a deep-seated inferiority complex and a longing for his first love. His inner world, perpetually unsettled by the slightest breeze, is thrown into violent upheaval the day he reads an essay by Lee Gang (Choi Hyun-wook), a student who sits in the back row. Lee Gang's pen draws Heo in from the razor-thin line between voyeurism and observation, and as it becomes entangled with Heo's festering sense of defeat, it flings open the door to an unstoppable catastrophe. The dense performances, the prose, the dialogue — all of it conspires to build a suspense that jolts every sense awake. This is the Netflix original series "Notes from the Last Row."

Released June 26, "Notes from the Last Row" stars Choi Min-sik and Choi Hyun-wook and is based on the play of the same name by Spanish playwright Juan Mayorga (El chico de la última fila). French director François Ozon previously adapted the work for the screen under the title "In the House" (Dans la maison). This series is helmed by director Kim Gyu-tae, known for his psychologically nuanced work on the Netflix series "The Trunk," the drama series "Our Blues" and "It's Okay, That's Love."

The Netflix series borrows the source material's metafictional structure — a professor reads a student's essay and becomes increasingly absorbed in it, as one story unfolds inside another — and reshapes it for the screen. Lee Gang's writing becomes a second narrative axis, and as Heo Mun-o grows ever more lost in it, he ultimately loses his way in the swamp between "reality" and "fiction." The question that surfaces without warning — where does reality end and the novel begin? — refuses to let go all the way through the final scene, and it is a burden the viewer must carry alone.

Heo Mun-o carries another label alongside his professorship: failed writer. He has no hesitation calling his students' work "garbage," yet he has never been able to shake the cutting remark made by Kim Su-hun (Heo Joon-ho), a college classmate who became a successful author. "You need to go back and relearn how to write a sentence," Kim once told him. Heo has spent his entire life chewing over those words. What remains is an inferiority and sense of defeat too embarrassing to show anyone; the creative desire he actually needs has long since gone dark.

Into this life walks Lee Gang, the student in the back row. Lee Gang shatters the self-assurance Heo has built on a foundation of denial, then shakes him to the core with an essay submitted as a class assignment. Convinced he has found a diamond in the rough, Heo invites Lee Gang to take private literature lessons with him. In his imagination, a future has already unfolded in which a successful author named Lee Gang credits his "mentor" at an awards ceremony. Heo projects his unfulfilled dreams onto the young man and becomes obsessed with making him his protégé — crossing lines, for the first time in his life, that should never be crossed.

The writing that has pulled Heo in reads more like a field observation report. Lee Gang, who works part-time jobs to get by, encounters what appears to be an ideal middle-class family through his classmate Kim Se-yun (Lee Jin-woo), and he deliberately draws closer to Se-yun in order to observe that family up close. His essays record in full, through Lee Gang's own eyes, the daily life of someone else's household — Se-yun's father and mother, Se-yun and his sister, even the housekeeper.

Lee Gang's murky intentions as he insinuates himself into Se-yun's family, and the ethical discomfort of watching him drift between voyeurism and observation, leave Heo uneasy. But the sheer force of Lee Gang's storytelling smothers every doubt and only sharpens Heo's hunger. Then one day, Heo realizes that Kim Se-yun is the son of Kim Su-hun — the very man he has always wanted to defeat. The household he has been peering into through Lee Gang's writing is Kim Su-hun's home, and the warm, beautiful mother in the story is Ahn Eun-ju (Kim Yunjin), the first love he never got over.

This revelation, the final piece of Lee Gang's narrative, obliterates whatever boundary between truth and fiction Heo had managed to preserve in his mind. He begins to want Kim Su-hun's true face — the man hiding behind the mask of successful author and devoted middle-class father — exposed through Lee Gang's writing, and in pursuing that, he does not hesitate to intrude upon and manipulate other people's lives. A wounded conscience is salved with hollow justifications: it is all "for the writing," all "for the sake of truth." Can Lee Gang bring this runaway story to a close? And where does Heo Mun-o's manic drive end?

If one word could best capture "Notes from the Last Row," it might be mastery. From Choi Min-sik on down — Choi Hyun-wook, Heo Joon-ho, Kim Yunjin, Jin Kyung — not a single member of the cast shows a crack. The subtle nuances, meanings and emotions packed into a single line of dialogue or a single sentence dissolve naturally and completely into the actors' performances.

The face-off between veteran Choi Min-sik and newcomer Choi Hyun-wook is particularly electric. Uncontrollable inferiority, petty impotence, boiling excitement and madness, euphoria and despair, fracture — all of it lives inside Choi Min-sik. Choi Hyun-wook's hollow eyes and expression, which instinctively signal the absence of truth, are the very engine of the drama's plausibility. The sequence at the end of the first episode — where Choi Min-sik soars through a scene of exhilaration and frenzy, like a bird freed from its cage — is a reminder of a veteran's craft that seems to know no ceiling.

The narrative and direction, which bind the beginning and end of the series tightly together and never allow the tension to slacken, are equally striking. Director Kim dismantles the rigidity of the frame-within-a-frame structure entirely, leaving both the characters and the viewer swimming in a space where neither can be sure what is real. The score — drawing on saxophone, clarinet, guitar, cello and more, carefully modulated in volume and intensity — keeps the immersion from ever going slack.

"Because the stories are layered inside one another, I thought the boundary between them needed to stay loose for viewers to sink deeper in," director Kim Gyu-tae said. "I paid close attention to the pacing, the narrative flow and the actors' performances to make sure audiences could lose themselves in Lee Gang's writing."

Early in the series, Heo Mun-o meets Kim Su-hun and obliquely delivers his verdict: that Kim is a populist writer. Kim's reply is direct: "What could be more thrilling than a writer and a reader being perfectly in tune with each other?"

That exchange finds precise form in the relationship between Heo and Lee Gang. Writer Lee Gang zeroes in on exactly what reader Heo Mun-o thirsts for, and Heo becomes consumed by the very kind of populist writing he has always scorned. In the process, the act of invading another person's life in order to write what a reader wants is deeply, irreducibly uncomfortable. Reality distorted and voyeurism dressed up as creativity — nestled inside a suspense that never allows the eye to wander is a weighty question about the relationship between art and ethics, desire and creation. Rated for viewers 15 and older.
