I really dislike the way the time-loop trope has developed over the years.

I don’t know where it originated or when it was first used, but it entered the mainstream with the 1993 comedy Groundhog Day, a film I remember enjoying for its dark humour. Suddenly, it seemed like every television show with a sci-fi premise attempted to find ways to include a time-loop episode before the end of its run.

The trope has two fundamental problems. The first is that it’s inherently low-stakes. Characters can die in spectacular fashion, but it hardly matters when the next loop simply restores everyone as though nothing happened.

The second is that it almost always hinges on one character inexplicably discovering they are in a loop despite everyone else remaining oblivious. The protagonist is simply handed the insight because the plot requires someone to break the cycle.

And suddenly, a trope that Groundhog Day handled with real psychology and moral complexity became mostly a predictable plot gimmick that offered diminished returns.

I am so done with time-loop stories…or so I thought.

The truth is that there is one aspect of the time-loop story that is appealing. It makes viewers participate, rewarding them for being aware of subtle changes in every loop. It is the element that has made something that has turned cliché still enduring.

Director Genki Kawamura was probably aware of this when he was developing the script for Exit 8. Or maybe it was simply an accidental consequence of adapting a puzzle-solving indie video game built around spotting inconsistencies into a film. Regardless, I have to give Kawamura credit because he fixes the two major issues I have with time-loop stories. The film still has a looping structure, but it doesn’t rely on repeatedly resetting time. Instead, the subway corridors loop while time itself continues moving forward, allowing consequences to accumulate. Although the puzzle occasionally appears to reset—for example, when the yellow poster returns to zero—the protagonist is not sent back to an earlier point in time. In this loop, a miscalculation at the wrong time can cause him to end up a mindless drone, endlessly wandering as a part of the puzzle. So the stakes are high. And because he is never reset to a starting point, his agency is never called into question. His déjà vu develops naturally from experiencing the same spaces over and over while desperately trying to reach the surface.

So yeah, if you haven’t figured it out from my writing by now, Exit 8 follows a man in a subway station who finds himself looping down the same four corridors on his way to the exit. And just to make things a little bit creepier, he sees the same man coming towards him every time he makes one of the turns in the loop.

Sometimes he sees a yellow poster that has “one.” Sometimes it says “zero.” Eventually, he spots an odd set of instructions: “If you find anything out of the ordinary or different in the hallway, turn back immediately.” And, “If you do not find any anomalies and the hallway looks completely normal, do not turn back.”

And with those simple instructions, Exit 8 makes all of us active viewers in the story, trying to spot the less obvious anomalies. I even ended up rewinding a scene where the protagonist failed to spot one and still am not sure what went wrong. (Though I now have a guess.) And I have to wonder how many anomalies I did not catch before our protagonist found the poster stating the rules.

Now I am intentionally leaving a lot of the plot out and am only sticking to what fans of the video game would already know. But there is, to Kawamura’s credit, more to the story. The main character gets to have an arc that expands past the simplistic “I need to survive” and “I need to get out of here.”

But a film like Exit 8 wouldn’t work if Kawamura wasn’t so apt at applying advanced storytelling and camera techniques. The film itself takes place in real time, often with extremely long, well-crafted shots. The opening, like the video game, is one long, impressive POV shot. We also, cleverly, get to follow more than one character before looping back to our main protagonist. Then there’s the question of what exactly is an anomaly, which requires real viewer engagement and is made more complicated when regular people lost in the corridors intersect. It is a very well-thought-out way to respect the video game while knowing a film needs to move beyond these limitations.

Because Kawamura is so aware of what he wants on the screen, he is able to turn what is essentially a gimmick film into a unique atmospheric horror experience.

J-horror may be long past its heyday, but that doesn’t mean innovative horror films aren’t still coming out of Japan. Like Shin’ichirō Ueda in One Cut of the Dead, Kawamura moves beyond the long-haired ghost girl archetype and the pressure to outdo his peers with increasingly extreme imagery. Instead, he finds something genuinely new in the language of cinema itself, using the film’s structure to reinvent a premise that had long since become stale.
