REVIEW: ‘Wall To Wall’ Crumbles Under The Weight Of Its Twists

Wall to Wall (2025) seems like it would be built on a solid foundation. However, the longer one treads behind its conspiratorial walls, the shakier the foundation uncovered. It’s a shame because with all of its varying themes, it could have been a lot more impactful. Instead, in his latest venture into the thriller genre, writer/director Kim Tae-joon throws too many ideas at the wall, rendering what could have been capable twists into distractions.

Woo-sung (Kang Ha-neul) emerges as an all-too-relatable protagonist. In 2021, he does everything he can to secure the dream home, an 84-square-meter (roughly 904-square-foot) property. A fuzzy-filtered montage reveals his efforts, ranging from selling land to taking out a loan, Woo-sung succeeds. It is initially a moment of joy, but three years later, his life has evolved into a nightmare and, unfortunately, there is little sympathy directed his way.

Previously engaged, he is now single (a plot point that is never referred to again). After taking out loans, Woo-sung is drowning in debt. To save money, he rarely uses electricity, including limiting his AC usage. His debt stifles him, much like the stuffy air and cloying heat of his apartment. The icing on top of his stress and misery is the constant banging on the walls as soon as he gets home, with escalating amounts of sticky notes placed on his door, blaming him for the noise. This noise puts a target on his back that only gets larger the worse the noise gets.

Home ownership turns ugly in Wall to Wall (2025), and in its first half, it is incredibly tense.

The first half of Wall to Wall (2025) is a tense, steadily escalating thriller. The scenario Kang Ha-neul plays Woo-sung as rightfully exasperated, with a hint of naivety that makes him the perfect protagonist to experience these things. There’s just enough humor from his physical performance to provide some levity, even as he suffers. Kim Tae-joon crafts a literal nightmare in the first half, grounded in a reality that anyone could picture themselves in. Who among us would not also be driven to madness with constant noise when trying to sleep?

With everyone homing in on Woo-sung, one of the couple of homeowners in the complex, he is not missed. The owners versus renters debate is one of the varying themes present, as a rapidly declining real estate market spells trouble. When initially meeting with the residents’ representative, Eun-hwa (Yeom Hye-ran) tells Woo-sung to be patient and wait things out after a frightening confrontation prompts him to file a complaint. Driving the undesirables, i.e., the weirdos she doesn’t want in the complex, tells us immediately what Eun-hwa is about.

Even still, the people who surround Woo-sung in the apartment complex are wrapped in mystery. This lack of knowledge highlights the growing sense of isolation he feels. A horrendous nightmare sequence (though deploying the dream within a dream trope that should be retired) exemplifies the anxiety that’s building. And when things finally reach a fever pitch halfway through, with an intensely, yet weirdly funny, race against the clock moment in a police station, it almost seems like we should be nearing the end.

The execution of a larger conspiracy does too much in an already complicated thriller.

After all that ramping up of energy, the story decisions made in the latter half of Wall to Wall (2025) fail to maintain the hype. Part of this is due to the natural high Tae-joon has already reached. What comes up must come down, after all. In an attempt to keep the adrenaline flowing and Woo-sun and the audience guessing, new twists emerge. Yet, some of the twists feel tacked on, likely due to execution and falling into tropeish territory. 

This doesn’t stop Tae-joon from trying to intensify things. Conspiracies are revealed, with technology proving, once again, to be used for evil rather than good. The weaponization of technology continues to be fertile territory for the director to play in, yet its inclusion and how it is revealed don’t quite land. Instead, with each new reveal, it almost seems like an attempt to one-up, even with breadcrumbs to guide the way.

With little room to breathe and let these ideas percolate and sink in, Wall to Wall (2025) ultimately falls apart, dragging its pace and story down with it. There is such a thing as too much of a good thing. In the case of Wall to Wall (2025), there are too many ideas fighting for supremacy. It almost makes it seem like two films are trying to fit in one, with a natural cut-off point somewhere in the middle.

Unfortunately, much like the building Woo-sung occupies, Wall to Wall (2025)  has its issues with no easy fixes. And despite the incredible performances in this thriller, the foundation it rests upon starts to crumble once things run out of steam.

Wall to Wall (2025) streams exclusively on Netflix July 18.
