Movieman630’s review published on Letterboxd:
Train to Busan is a solid Zombie action film. The film takes the rage zombie idea of 28 Days Later and throws it into a more hyperkinetic claustrophobic setting. The first act of the film is especially effective. It slowly builds up its protagonists and tension, hinting at what’s to come before suddenly letting the shit hit the fan.
The film does start to drag as it goes on. Though the filmmaking is solid, and it does have some fun scenarios for the characters to survive, it starts leaning more heavily into cliches. As well, the more action heavy focus means that the zombies never feel quite as threatening as they should.
Still, credit must be due to the filmmakers for keeping a sense of energy throughout the run time. As well, the performances are strong, for the most part. Though the “villain” character is more annoying than anything (admittedly more of a writing issue than an acting one) Ma Dong-Seok gives an especially powerful performance as the Deuteragonist.
Overall this is more fun than scary, but that’s not really a problem. It’s a zombie film that perhaps hews too closely to the playbook, but has just enough new ideas to stay interesting.
