I stumbled across this by accident and gave it a try on the basis of the great reviews. This is by far and away the best zombie film I have seen. Everyone in it is great and you find yourself really caring about the characters who have interesting and realistic shades of light and dark. The zombies are worthy of their own award. I've become increasingly frustrated by slow moving, shambolic zombies as in The Walking Dead. However the zombies in Train to Busan this are mesmerising and terrifying. There are lots of them, they are very fast, extremely aggressive and the way they walk, look and twitch is brilliant. I can't recommend this film highly enough. It's rare to find a film that doesn't sacrifice one element for another such as the plot in favour special effects.
