"One of the most stressful movies I've ever seen": It's the most popular on Netflix Spain, and it will make you love your neighbors.

It's one of the most talked-about psychological thrillers on Netflix Spain, and for good reason: the tension it exudes is intertwined with the pressure and nighttime noises the protagonist perceives in a suffocating atmosphere. The film, which ranks number 10 on the popular streaming platform this week, reflects a concern increasingly present in large cities: the emotional toll of living in a community.

The film, titled My 84 m² , is a South Korean production that has generated conversation for its social criticism hidden in a suspenseful tale. Directed by Kim Tae-joon, this story features Noh Woo-seong, a thirty-something office worker who, after years of effort, manages to buy his first apartment .

But what seemed like a dream turns into a nightmare with literal echoes: constant noises, hostile neighbors, and a growing paranoia that threatens her sanity. As the director himself stated to KBS , the story "deals with the collision of diverse desires in a very Korean space ."

The real terror

The film serves as a mirror to a troubling reality in South Korea , where noise between apartments has gone from being a nuisance to a serious social problem, with thousands of complaints filed each year. Furthermore, the title is no coincidence: 84 square meters is the typical surface area of standard housing in Seoul and, in this case, the setting where the entire conflict unfolds.

The film, with clear reminiscences of Parasite for its critique of the real estate system, moves between everyday horror and psychological drama. Kang Ha-neul's performance has been particularly applauded for its portrayal of the protagonist's anxiety and emotional deterioration . Specialized blogs such as Heaven of Horror have described it as "One of the most stressful films I remember seeing."

Its success on Netflix confirms the interest in Korean stories, which combine narrative tension with social criticism. Beyond its plot, this production leaves us with an uncomfortable reflection: sometimes, true terror lies not in supernatural creatures , but in everyday life—or, in this case, in the upstairs neighbor .
