Clever in its action-horror set pieces, but the massive loss of life is is quite apathetic with so many vapid and tepid characters, while the family drama of its leads is rudimentary. It should've began on the train and built all of its characters and story up from that setting onward. Many less characters could've worked wonders, allowing time for its melodrama to become drama, and more deaths to be emotional.
Probably has the deepest emotional core of any zombie film up to now, naturally leading to it also seeming like one of the bleakest. Class politics are used to drive the action beats (like 90s action films) instead of taking over the dialogue as the themes and social commentary are interwoven with plot and character expertly enough to be a kind of physical allegory. Kim Su-an puts in a uniquely raw performance.
people expecting this film to be a well-thought out plot with character development, look away. it's a zombie-gore-action packed film where no one's left behind - some people fend for themselves while others stay together. i personally watched this film for Gong Yoo (who starred in this epic kdrama called Goblin) and wasn't disappointed.
I was surprised with how good it actually was. It is the best use of the "fast/rabid" kind of zombie since the remake of Dawn of the Dead. Wouldn't say its scary but it is enjoyable and has moments where the tension builds nicely. Overall a refreshing change of pace and a step above the majority of the stagnate fodder thats gets released within the zombie genre nowadays.
