The first few episodes seemed interesting, but even with the slashing, blood and gore, it wasn't enough to hold my attention. When the ML switches to more of a current time line, the flash backs become redundant. The writers seem to be madking it us as they go. The weird out of focus cinematography gave me a headache and didn't add to the drama at all. The monsters have really crappy makeup and you can even see the contacts for their eyes. Their nails are supposed to be able to slash, but when you get a closeup of those same fingernails, they aren't even sharp. Continuity issues as well.

The actors try their best, I kept watching because of Lee Joon's acting for his character. But the predictable plot and lack of wow moments, didn't help and trying to create romance between certain characters that had no chemistry, seemed just an add on. This drama-thriller seems to borrow concepts from other dramas, but not in a good way.

I dropped it after 7 episodes. Others rave about this new drama, but I'm just disappointed and feel let down by the writing. Overall 5.5/10
