|X was the real Y||It turns out humanity was the real trainful of zombies.|
This has been a good few years for Korean train and horror movies.
I liked this a bunch. The train was a great setting for a zombie movie, the characters were good (well, some were jerks, but that was the point), a lot of the drama was humans against eachother not humans against zombies, and they even used the word 'zombie'. Would recommend.
