WOW. I just finished this.

Let me start by saying it is definitely very gorey. If you can't stomach that, you should stay away from this drama.
But it is so much more than just gore: The monsters are, at least in the beginning, incredibly fun to watch. It has a certain comic/anime feel to it. The acting is incredibly good and the music fitting, both in action-loaded an emotional scenes.

I loved the setting of this run-down house with all these characters that have somewhat lost their way in life but are rediscovering what it means to be human and alive.

In the end, the real monsters are not always those that have transformed, but those within us. The season finale was epic. I cannot wait for more. I also really really love Song Kang in this role - amazing acting with adorable monster eyes.
