A review by samsalabäm

You don't get too many korean shows with a cool and clever female lead. Inspector Koo is one of this rare diamonds where a women isn't just the female love interest. I really would love to watch a second season. There is crime and murder and a bit of nerdy stuff. I enjoyed it a lot.
