If you like Supernatural (American tv) this show hits all the right spots. Also if you like Master's Sun you would also enjoy this. The main show is a mix of campy ghost bits episode to episode with an overarching story with the main character that IU plays. It's a really well filmed/directed show and even the CGI is integrated well that it's just a good watch. The music was very well suited too.

I've been waiting for this show for a while since it's directed by the same director of While you were sleeping (one of my all time faves) and he didn't let me down. The writing however I was a bit disappointed that it was pretty much exactly what I expected since the ghost side stories felt very similar to Master's Sun. The upside is that all of the side characters were all very lovable (not a single overly annoying or over the top characters) and had pretty good handling/screen time unlike some of the other works by the Hong sisters. The main leads did justice to the overall theme and type of character they had but I didn't really feel the chemistry between them, so their eventual relationship wasn't my fave. I think the overall arc would still be equally good if YJG was just a devoted worker and not in love with her. However I hope that YJG gets a definitive happy ending in a drama soon. His dramas this year isn't that good for that lol.
