Thriller, crime, law, with suspense & dark ambience. Ambiguous protagonist. Gray area between good-evil. There is no ultimate truth, human are naturally imperfect beings. Shin Ha Kyung is main actor on both dramas. Both dramas are about the journey of duo partner crime.
We will get beautiful, smart and charismatic psychopath as villain in both dramas (Eun Sun Jae & Song Yi Kyung). Those villains have a complicated and weird relationship with the main character ( Woo Tae Suk & Koo Kyung Yi)
It has a similar vibe. It depicts a same kind feeling of helplessness even if its roots are different. Their soundtracks are a work of art. Less than evil may focus its attention on the policeforce and its flaws while Cruel City shows the people living on the other side of the law.
