A gripping new South Korean sci-fi thriller has made a huge splash on Netflix, leaving viewers emotionally overwhelmed and drawing immediate comparisons to Hollywood blockbusters. The Great Flood, which began streaming on Friday, 19th December 2025, features a major star from the platform's most-watched show ever.
A Bleak Vision of the Future
The film presents a harrowing disaster scenario where a cataclysmic global flood threatens to wipe out billions of lives. The narrative zeroes in on a desperate mother, uniquely equipped with a plan to save the planet, who must simultaneously fight for her own child's survival as rising waters trap them in their apartment building. This emotional core has resonated powerfully with audiences, sparking an outpouring of reactions online.
The cast is a major draw for fans of Korean television. The film stars Kim Da-mi, celebrated for her role in Itaewon Class, alongside Park Hae-soo, who shot to global fame for his performance in the first season of Netflix's phenomenon, Squid Game. Their involvement has generated significant buzz for the project.
Viewers Left Breathless and in Tears
Since its release, social media and review platforms have been flooded with passionate responses. Many viewers have reported being moved to tears by the film's intense survival story. One user on X declared, "Just watched #TheGreatFlood....I am ugly sobbing rn. Why is it so emotional!! Kim Dami's choices are always masterclass!!"
Another fan admitted the film's power was a surprise, posting, "watched the great flood on netflix since i was looking for films to watch while eating. anyway its not a good film to watch while eating but its a good film to watch if u want a good cry." The praise extended to dedicated film sites like Letterboxd, where one five-star review noted the film's evolving cinematic style, stating it felt like The Day After Tomorrow before shifting into Interstellar territory, and ultimately calling it "Easily one of the best movies of 2025".
Critical Acclaim and Genre-Bending Praise
Critics have also lauded the film's ambitious scope and daring narrative. Online publication Baap of Movies described it as a "Korean Apocalypse That Dazzles, Divides, and Drifts into Dark Sci-Fi," highlighting its bold ideas and genre twists. The Guardian labelled the thriller "sinister," pointing out influences ranging from Edge of Tomorrow to the complex mind-bending works of Charlie Kaufman and the epic scale of Christopher Nolan's Interstellar.
The consensus, as summarised by Gulf News, suggests that The Great Flood is a must-watch for enthusiasts of high-stakes, suspenseful cinema that isn't afraid to blend genres. With its potent mix of spectacular visuals, emotional depth, and star power from the Squid Game universe, the film has firmly established itself as a major talking point in Netflix's end-of-year lineup. The Great Flood is available to stream globally on Netflix now.
