Sean Kelly’s review published on Letterboxd:
2016’s Train to Busan was an immensely action-packed affair that showed that there was still some life in the overplayed zombie apocalypse film. Automatically it would be impossible for Peninsula to be seen on the same level as the previous film and indeed this film falls into the typical zombie film cliche of the fellow surviving humans being more dangerous than the undead threat.
However, if there is one thing I can praise director Sang-ho Yeon for is that he made three connected zombie films that were completely different from each other, whether it be the animated presentation of Seoul Station or the intense action of Train to Busan. With Peninsula, Sang-ho Yeon goes in a direction that can be seen as more akin to post-apocalyptic films such as Mad Max or Escape from New York. Indeed one of the major set-pieces of the film has a captured Chul-min being forced to compete in a Thunderdome-like fight against zombies. Peninsula also features one hell of a car chase that makes up the bulk of the film’s climax.
Overall, while Peninsula doesn’t quite have the same level of originality as Train to Busan, it is still a quite solid post-apocalyptic zombie action film.
