I have watched at least 50 K Dramas and honestly although I've lost count, this I must say is my all-time favorite. Is it worth watching? Definitely! It has all the elements of a perfect production from cinematography, casting, to storyline. It is so entertaining since it combines all the possible emotions rolled in each scene and incorporates all facets of fantasy in the afterlife, horror, romance and comedy. It will make you cry and laugh and for certain , will make you temporarily forget your day-to-day concerns.
