Never underestimate the power of a disaster movie. In a twist that surprised analysts and critics alike, the South Korean sci-fi thriller The Great Flood achieved a historic feat at the end of 2025: it dethroned the colossal Wake Up Dead Man: A Knives Out Mystery.
The film hit #1 in 71 countries, cementing itself as the blockbuster of the moment. But what explains this overwhelming success in the face of lukewarm critical reception? If you haven’t watched it yet, here is why you need to check it out—caveats included.
Spectacle vs. Critics
It’s impossible to ignore the elephant in the room: The Great Flood is not universally loved. With a modest 5.3 average on IMDb and only 60% approval on Rotten Tomatoes, the film directed by Kim Byeong-woo divides opinions. The press points out script flaws, but the global audience doesn’t seem to care.
Why? Because the movie delivers exactly what it promises: visceral tension. The premise of an asteroid melting the polar ice caps and trapping a scientist (An-na) in a building that is progressively sinking is executed with an urgency that grips the viewer. It is the type of cinematic experience that, despite narrative shortcomings, offers pure entertainment and adrenaline—something that often trumps the search for “high art” on the living room couch.
Why Should You Watch It?
In a world saturated with sequels and franchises, seeing a Korean production knock Detective Benoit Blanc off the top spot is a cultural event. Watching The Great Flood right now is joining the global conversation. It’s about understanding how Asian disaster cinema continues to evolve visually and why, sometimes, a 5.3-rated movie can be more fun and engaging than critically acclaimed works.
