Netflix's Gyeongseong Creature is a mix of creative elements. It has the romantic flair of Korean dramas and soap operas, detailing a morbid story of Tae-sang and Chae-ok trying to be with each other in a time of war in Korea. However, it has the vibe of Stranger Things and Venom, with Chae-ok's kidnapped mother, Seong-sim (aka Seishin), turned into a monster at a hospital in the province of Gyeongseong. It occurs during the Japanese occupation of Korea in the 1940s, with Lady Maeda's Japanese scientists experimenting on victims from the Joseon region.
