This is an another epic of Asian dramas. The cast crew was very awesome they made me to feel their character and really impressed by park hyung sik comeback after a long time. If I were there in the story I will really kill that doctor ahjusshi. The story was very addictive like I can't wait to watch next episodes. the concept is what we already watched in other zombie movies but till the end of the drama there were full of twist and turns that you will never think this would happen. 1st I started to watch happiness because this is park hyung sik's comeback after strong women do bong soo. he never made me feel disappointed in both of these dramas. han hyo joo's comeback was also really great after watching in W (the two world) she done her job as a female lead here super awesome well! she made me yto fell for her once again. I don't know what are others opinion but this is really worth to watch it. please don't miss it out
