It’s another strong demonstration of how Korean filmmakers approach zombie films. Similar to Train to Busan, this film offers a fresh perspective on the familiar ideas instead of simply rehashing what's been done before. A palpable sense of immediacy permeates the movie, and both the performers and creative team manage to convey that effectively. The special effects are top-notch, and the entire production feels expertly handled. I found it very entertaining, and would suggest it to those who like zombie stories.
