Train to Busan is a South Korean zombie movie. The bulk of the movie takes place on the high-speed train, the KTX, as it leaves from Seoul to Busan.
The zombies in the movie are reminiscent of the ones in the cinematic version of World War Z or 28 Days. They are a strong and swift horde that engulfs anyone in their path, spreading the sickness within seconds of being bitten. In the realm of zombies, Train to Busan doesn’t offer anything new. As an audience, we have seen these types of zombies before. But the other aspects, like the pacing and characters that make it a blockbuster.
The pacing of the movie is well done. The outbreak doesn’t happen suddenly, rather it builds into the catastrophe.
