I love this show!! Definitely one of my all- time favorites, and one of the few k-dramas that i have re-watched. This show is so creepy, an excellent horror show. I'm a big fan of Kim Jae Wook, and i really enjoyed his role as the 'hot' priest (ie he is so good looking and such an excellent actor that he could vacuum for an hour and i will happily watch! ) He and the rest of the stellar cast do not disappoint!! Right from the beginning, it is set up like an interesting mystery ( who is Park Il Do), and it holds the suspense and tension all the way through, it makes for excellent binge watching.
