“One Ordinary Day” (어느 날)

As Hyun-soo, Kim Soo-hyun is superb in a difficult role where he has to be sympathetic, but also could be a cold-blooded and manipulative killer. His role requires him to cry in a manner that allows viewers to feel his panic and fears. And Kim comes through again superbly, proving he is one of the best actors of his generation.

“Emergency Declaration” (비상선언)

In the span of time it takes for a plane to fly from Seoul to Honolulu — approximately nine hours — a psychopath boards an airplane at Incheon International Airport and releases a deadly biological pathogen onboard, which results in passengers getting sick and/or dying (and turning on each other). And, oh yeah, scientists on the ground  develop an antigen to combat the virus.

“Yumi’s Cells” (유미의 세포들): Season 1

Yumi is a woman in her early thirties, who had spent most of her twenties with a man who used her financially, cheated on her and then left her after seven years together. She viewed those as wasted years and, in some ways, is correct. Doting on a partner who doesn’t value you is nothing to be proud of. But there’s also something to be said for learning from negative experiences.

“Hellbound” (지옥)

Director Yeon Sang-Ha (“Train to Busan”) adapted “Hellbound” from his own webtoon of the same name. He makes it clear that cults are the true sinners, which manipulate people’s lives with fear. And that hell isn’t necessarily a place foreign to us, because it’s where we may already be living. 

“D.P.” (디피)

The superb “D.P.” is not an easy series to watch. While not as gory as “Squid Game,” it’s more disturbing in many ways, because it deals with South Korea’s real-life mandatory military duty — which requires every able-bodied Korean man to enlist for approximately two years.
