Why this new Netflix sci-fi film is massively disappointing viewers

The South Korean film “The Great Flood” – French title: Submersion – attracted strong criticism upon its release on Netflix. Viewers denounce its confusing plot and its production as clumsy. With Kim Da Mi and Park Hae Soo starring, expectations were very high, but the film quickly disappointed and caused strong discontent on social media.

The story begins with a gigantic flood that submerges Seoul and strands residents in buildings. Very quickly, the story turns into a strange mix of science fiction and forced emotional scenes. The realistic survival sequences that audiences were hoping for give way to passages that are difficult to follow and unclear.

On theqoo, Internet users criticize the disorderly editing and the lack of logic in the scenario. A viewer explains: “It felt like the director wanted to make his own version of Interstellar, but he didn’t succeed.” Others point out that the film treats the audience as if they lack intelligence, offering “zero depth and maximum confusion”.

The dramatic style of the film is considered outdated and exaggerated. The sad scenes seem forced and empty, and many denounce the role of the child, used only to arouse emotions. A viewer asks: “Was the child supposed to be a punching bag for all emotions? »

Despite these criticisms, Kim Da Mi and Park Hae Soo’s performances were praised for their sincerity and depth. However, even this acting was not enough to save the film. Internet users expressed their anger:

• “The director should seriously consider a new career. »
• “The plot deserves a zero. This isn’t a disaster movie, it’s a disaster movie. »
• “The acting was correct, which made the bad script even more painful. »
• “I usually cry at emotional scenes. This time I stood there like a stone. »
• “Was the child character written just to be annoying? »

The release of “The Great Flood” also reignited fans’ frustration over the edits made in “Omniscient Reader” by Kim Byung Woo. The film was reportedly finished before “Omniscient Reader,” but its release was delayed for unknown reasons, furthering confusion around the project.

As 2025 draws to a close, “The Great Flood” is already considered one of the worst Korean films of the year. With two consecutive failures, Kim Byung Woo’s reputation as a director remains strongly in question.
