Initially, I was very skeptical about this drama because I do not usually watch supernatural dramas. However, I was pleasantly surprised because it turned out to be very good. The build-up was great, I haven't encountered such a neat storyline progression in a while. Unfortunately, most dramas start out strong and only get worse by the episode, however this only got better with time. The ending might have been my favorite part, which is a hard thing to achieve. It left me wanting a second season but was also satisfying enough so that it didn't feel incomplete. Of course, there were some things I didn't like or would have preferred if they'd been executed differently, but overall, I would definitely recommend this drama!
