Train to Busan was truly one of the greatest zombie movies ever made, leaving viewers eager for more of something similar. As a South Korean story of not just survival but also parenting, selflessness, and sacrifice, director Yeon Sang-ho managed to create a thoughtful story that was as profound as it was action-packed. While there are plenty more great South Korean zombie movies to check out, there are plenty more fast-moving zombie releases from around the world that echo the appeal of this modern horror classic.
