Train to Busan is a South Korean zombie apocalypse film. It mostly centers on businessman Seok-woo (Gong Yoo) who is taking his daughter Su-an (Kim Su-an) to her mother's and they're taking a commuter train to do so. A zombie outbreak has occurred overnight and as the train leaves the station the passengers see zombies attacking people. And there is an infected on board who soon spreads the zombie diseases to passengers.

During most of the trip the train heads to Busan, the last known safe city on the line. Meanwhile passengers struggle to contain the zombie outbreak. Midway through the film there is a scene where the train stops at a "safe" city. Passengers debark and are attacked by zombies. As they rush back they are split up into two groups with zombies in between. Seok-woo and some fellow survivors have to travel through four zombie-filled cars to reach their loved ones.

It's a good action film that remains suspenseful throughout. The characters are fairly distinct. I like one of the zombie weaknesses which I haven't seen before in zombie movies. I liked the ending with a callback to an earlier scene where dad missed his daughter's recital. Overall a good film.
