This show was amazing. It had my heart beating really fast on almost every episode. I'm not really the melodrama type, but the whole revenge thing I read about tweaked my interest, but the 20 episodes turned me down, because I don't really watch dramas with more than 16 episodes because I think they drag, but Heartless City really was fast paced and it didn't drag. I finished it all in one day. The music was well fitted and placed in the right scenes. I really hate it when the music doesn't go with the scene. Jung kyung ho really shocked with his serious acting. Every time I turned a corner a new secret punched me in the face. All the plot twist were placed really well and revealed in a good way. They were placed throughout the show. I would have to wait until I forget all the secrets to be able to rewatch this show.
