Breaking all sorts of records in its native South Korea, Train to Busan shows that there is still some gas in the tank of the zombie apocalypse genre of horror film. While "zombies on a train" may sound like a gimmick in writing, Train to Busan is a quite well executed film that is incredibly entertaining to watch. While the relationship, between Seok-woo and Su-an make up the main emotional core of the film, the film also focuses on a handful of other survivors, such as Sang-hwa (Ma Dong-seok) and his pregnant wife Seong-kyeong (Jung Yu-mi). As in many zombie films, the human threat can sometimes be great and Train to Busan features selfish and antagonistic businessman Yong-suk (Kim Eui-sung), who will absolutely be despised by the end of the film.
The zombies of Train to Busan are of the variety that chase after the survivors in large swarms. In the few scenes of the film that take place outside of the train, there are easily hundreds of zombies giving chase, with most of them (to my knowledge) being played by actual people. Probably one of most creative aspects of Train to Busan is the fact that the zombies will only attack if they see or hear a living person. This results in multiple sequences where the survivors have to take advantage of the zombies' limited vision in the darkness of tunnels in order to sneak past them undetected.
While Train to Busan features some very entertaining zombie-fighting action, there is a real emotional core to film. Pretty much everyone in the core group of survivors is likable, so it is quite sad whenever one of them becomes a zombie victim. Then there is the central relationship between Seok-woo and Su-an, which will likely pull at your heartstrings by the end of the film.
Altogether, Train to Busan is a quite entertaining Korean zombie film.
