Gyeongseong Creature (Season 1) | Korean Drama

Gyeongseong Creature Season 1 is a visually stunning K-drama that melds historical horror with monster thrills, set in 1945 Gyeongseong (now Seoul) under Japanese occupation. Park Seo-joon shines as Jang Tae-sang, a slick pawnshop owner turned reluctant hero, while Han So-hee’s Yoon Chae-ok, a fierce sleuth searching for her mother, brings grit and grace.

The show’s first seven episodes (Part 1) build a slow-burn mystery around Ongseong Hospital’s grotesque experiments, erupting into chaos with a tentacled creature born of greed. Part 2’s three episodes falter, losing focus post-hospital but delivering a gut-wrenching climax—Chae-ok’s mother as the monster, Tae-sang’s sacrifice, and a 2024 tease. The 92% Rotten Tomatoes score reflects its gripping production and cast chemistry, though pacing drags (10 episodes averaging 70 minutes) and CGI wobbles. It’s a compelling mix of colonial trauma and supernatural dread, not perfect but a genre feast for K-drama fans.
