The 6-minute rule
If you decide to hit play, tell everyone to put their phones away for the first six minutes. This isn't a movie you can "second screen" while scrolling TikTok. The opening lays out the entire Buddhist legend of the two eyes—one red, one black—that must never meet. If you miss that setup, the next 90 minutes will feel like a confusing fever dream rather than a supernatural thriller.
The film relies heavily on this specific worldbuilding. It’s not just about a monster jumping out of a closet; it’s about a spiritual countdown. While the "monk with an ax" premise sounds like a high-octane action flick, the reality is much more meditative. That’s where the friction lies. Critics appreciated the moody, artistic cinematography, but the low audience scores stem from the fact that it often prioritizes vibes over momentum.
Why the audience score is so low
That 39% audience score on Rotten Tomatoes is a giant red flag for a reason. Most viewers go into a Netflix horror movie expecting something like The Conjuring or Train to Busan. Instead, this is a procedural drama that happens to involve ancient demons.
The pacing is the biggest hurdle. There are long stretches of dialogue and atmospheric walking that can feel glacial if you aren't deeply invested in the lore. If your teen usually complains that movies are "too slow" or "nothing is happening," they will likely bail by the 45-minute mark. However, if they are the type of viewer who loved the dread of The Wailing or enjoys exploring how different cultures handle the "chosen one" trope, they might find the mythology rewarding.
How to gauge the "scare" factor
This isn't a "fun" scary movie. It’s bleak. You’re looking at bloody crime scenes, some fairly disturbing possession makeup (think grey skin and bulging eyes), and a heavy sense of doomsday.

If you have a younger teen who wants the "demon hunter" vibe without the crushing weight of a slow-burn Korean thriller, you might want to wait for lighter fare like the KPop Demon Hunters sequel. That franchise offers the same "supernatural team-up" energy but with a much higher entertainment-to-boredom ratio.
The verdict for your movie night
Skip this for a family movie night unless everyone in the room is a hardcore international horror completionist. It’s a niche pick. The cinematography is undeniably beautiful, and the way it weaves Buddhist philosophy into a horror framework is unique, but it’s ultimately a slog.
If your teen is dead-set on watching it because they’ve exhausted the rest of the Netflix horror catalog, suggest they watch it with the original Korean audio and subtitles. The English dub tends to flatten the performances, making the already-slow pacing feel even more wooden. It’s a movie that demands your full attention but doesn't always give you enough back in return to justify the effort.
