Kim Mu Yeol the man. He is doing fantastic job as action hero. Best action hero i have seen in kdrama. He shows intent in action. Intent to hurt. That is the missing piece in all fake stunts in kdrama. No posing just pure adrenaline rush. Where you have been so long?. I do not like lee shi young as cop. She is terrible. Go sung hee improved lot or may be this role better fit her. Generally casting of cops is terrible. This is my kinda drama. I like anything emotional action drama because it seems like real.
