I watched this a while ago, but I'm only putting this review here now. If you haven't watched it yet, it's definitely worth it. Pretty much everything is perfect, except that it is too long. One or two episodes inbetween could easily be shortened or removed entirely. The ending also let me down a bit, but season 2 hopefully will explain more of why the ending was the way it was. Be mindful though that it is gory and blood with many horror elements. Not exactly a lighhearted watch. What blew me away the most is the acting and I found many of my new favorite kdrama actors through this show. Would for sure recommend!
