On the 2nd Day of Halloween, I recommend to thee…
Train to Busan (2016): commuters trapped on a fast train with a horde of fast zombies.
That premise alone should instantly hook you! But should you need more, know that this film has so much that makes it great: strong characterisations, great gore, witty nods to genre classics, socio-political subtext, and an ending that will move you as much as it thrills.
Personally, what I like best about it is how they take an already confined space, and exploit every nook and cranny of it to create cracking set pieces full of claustrophobia and tension. 🚂🧟♂️
