This drama is what the title says Bad and Crazy. I loved the detective storyline and it brings awareness to those who have dual personalities or alter egos. Everyone has a good and bad side of themselves and some have bad and crazy in themselves. Lee Dong Wook (Ryu Soo Yeol) I love this actor and he is good at playing the character in this drama. Wi Ha Joon ("K"), I have to applaud this actor for his acting in the character he played. These two main leads, what a great collaboration. Actress Han Ji Eun (Lee Hee Kyum) played a strong lead and she was awesome. Cha Hak Yeon (Oh Kyung Tae) poor CHY he had was injured so many times I felt sorry for him but he became strong in the end. Amazing visuals, and a great storyline, I wish this was a recurring series. Thanks to all the Bad and Crazy team and the other supporting actors and actresses.
