I've watched all the episodes currently released! And i'd say so far so good (really good) i really enjoy watching the show, it does really keep you on edge sometimes (exciting!) I personallythink that there's a lack of supernatural shows in the drama world (especially in kdrama) and if it keeps going like this this will probably be my new favorite drama! The cast does really work together well, the endings do are very annoying because they'll always end with a cliffhanger! It's also a very good way to learn more about Korean culture, watching this show made me intrigued to search and research more about the nine-tailed fox and stuff!! I love it!!
