Film Review – Wall to Wall

July 19th, 2025 | POSTED BY Allen Almachar

Being a homeowner comes with its positives and negatives. On one hand, you get a place to call your own, to do as you please and to come and go whenever you want. On the other, you are financially tied to the space – you can’t simply pack your things and leave if the home doesn’t suit your liking. The issues only multiply if you live in a town house or condo, because then you must share a wall with one or more neighbors. Heaven forbid you have noisy neighbors, or worse yet, ones that complain about you being too noisy. Yes, it is great to own a home, but sometimes it can be a living nightmare. That is what lies at the heart of the South Korean thriller, Wall to Wall (2025).

Directed by Kim Tae-joon (who also supplies the screenplay), the narrative follows a young man named Woo-seong (Kang Ha-neul) going through a major life crisis. A few years prior, Woo-seong took his life savings to purchase an apartment in the heart of Seoul. While he finally got to move into the city like he wanted, the sale has left him house poor. He doesn’t have enough money to afford furniture, keeps the lights off to lower his electrical bill, and works two dead end jobs to barely make ends meet. Woo-seong is in such dire straits that he – at the advice of his coworker – considers dumping whatever money he has left into the crypto currency game.  

And then there’s the noise. Somewhere in the neighboring floors of Woo-seong’s building is a mysterious and incessant noise. It’s such a distraction that he must wear earplugs at night to sleep. But what makes it so mysterious is that he, along with his neighbors, can’t pinpoint where it’s coming from. The tenants below have left notes at Woo-seong’s door asking him to quiet down, even though he explained it is not coming from him. He visits other occupants on the floors above him, who all hear it as well but also say that they are not responsible. An air of distrust grows throughout the building, with everyone becoming suspicious of one another – with most eyes directed at Woo-seong. This, of course, is not what he needs right now. The ambiguity of the noise adds an additional layer of stress that Woo-seong cannot deal with. Not only does he worry about making money, he must also suffer with a noise that is slowly driving him up the wall.

In terms of tone and theme, Wall to Wall has similarities to Bong Joon Ho’s masterpiece, Parasite (2019). Both examine class struggle – how the haves and have nots are divided by distinct social lines even when existing in the same spaces. There’s also a visual parallel as well. Just as the characters in Parasite travel up and down the zigzagging roadways (a clear metaphor for economic divisions), so too does Woo-seong travel up and down the various levels of his building. One of the most memorable shots is a long-distance wide angle of Woo-seong’s building. We watch him slowly climb the staircase on his way to the building manager (Yeom Hye-ran) in hopes of finding some answer to the noises. 

The tension is at its highest when Kim focuses in on the central mystery. Yes, the economic elements are important and timely, but I was most glued into the story when Woo-seong’s anxiety over the noises escalate. There’s a sense of paranoia that builds throughout, with Woo-seong’s world slowly crumbling all around him. Kang Ha-neul delivers a very strong performance in the central role. He allows us to follow the character even as he falls into deeper desperation. It’s as though there is a conspiracy against him with everyone plotting his demise. The apartment manager, his neighbors – including a quiet tough guy named Jin-ho (Seo Hyun-woo) all seem part of the scheme. 

For most of the narrative, the suspense works because we – just like Woo-seong – are anxious to find out where the sounds are coming from. Sadly, the writing makes the grievous error of supplying an answer. Kim provides a definitive answer to the question, but by doing so drains the film of all its intrigue. Even worse, he does so way too early, spending a large chunk of time afterward trying to tie all the loose strings together. Sadly, once he reveals his hand, our interest in what happens next dissipates. Woo-seong’s relationships with his neighbors, the apartment manager, and Jin-ho resolve but are unsatisfactory. And his quest to make money and find his Happily Ever After comes off as contrived. It was strange to see the film deflate in such an abrupt and dramatic fashion. It makes me wonder what would’ve happened had the mystery of the noises were never answered at all.

Kim and the rest of the production allow for some clever cinematic sequences. The narrative isn’t shy about delving into flights of fancy. An opening montage features Woo-seong imagining making money from investing in his apartment and using that to marry the girl of his dreams. The cinematography and editing turn the montage into a lush, vibrant, and sun-filled haze. This is in stark contrast to a later scene, where Woo-seong suffers from an overload of stimulation. Every creak, bump, hum, crash, beep, clink, and alarm topple over him like a tidal wave of sound effects. He is pushed so far to his limit, and it takes all his will power just to get through the day. The two montages demonstrate how Woo-seong’s fantasy has become his burden – where his hopes have turned to despair.

Wall to Wall is two thirds of a great movie. Once we know all the secrets and hidden agendas is where things take a nosedive. Still, it’s such a captivating and bizarre experience up to that point that it might be worth taking the trip regardless of where things end up.
