Professor Se-jeong is thrust into a bloody nightmare when a rapidly mutating virus is released during a biotech conference causing authorities to seal the facility. Trapped inside with no escape, Se-jeong along with a small group of survivors must fight to stay alive while the infected undergo horrific transformations.
Critic Consensus
Critical reception for Colony is moderately positive, with reviewers broadly agreeing that director Yeon Sang-ho constructs a tense and unsettling atmosphere within a contained outbreak premise. The film's bold genre craft and consistent internal logic draw consistent praise. However, critics frequently note that the human drama and the film's deeper thematic ambitions — around surveillance, misinformation, and loss — are underdeveloped and fail to resonate as strongly as the premise promises. One dissenting voice found the film falls short of Sang-ho's best zombie work overall.

Updated“Yeon might be a very good student of the genre, and the deck he crafts is often masterful. It’s just that the communication lessons and memory of human loss don’t hit hard enough as genre lovers on the brink of some AI-enabled civilizational collapse need them to right now.”Read full review ↗
“Sang-ho succeeds in creating a thrilling and tense atmosphere, and the film follows its own rules.”Read full review ↗
“Yeon Sang-ho's Colony turns a sealed Seoul outbreak into a battle against evolving infected. Its bold ideas and unsettling atmosphere stand out, even as the human drama thins.”Read full review ↗
“Similarly, the narrative’s deeper ideas of surveillance, of the spread of information (and misinformation) as something of a virus, are also not explored in any great detail beyond adding an additional level of peril. But that may not matter to horror audiences and, as a modern zombie movie, Colony certainly has a satisfying bite.”Read full review ↗
“Despite some wincing sound and production design, Yeon Sang-ho fails to deliver the highs of his best zombie projects.”Read full review ↗
