This drama had a slow start, but bloody hell this series is so good. The character driven drama essentially is about the human relationships and their struggles against their own demons more than about the monsters. There's a good amount gore and humor that I often find in B movies (which I love btw), lots of blood, lots of action, lots of twists, amazing characters, STUNNING cinematography, love the soundtrack, and I'm pretty sure I now have a girl crush on the badass Lee Si-young.

Rewatch value - I almost never rewatch anything, same goes with this one.
