Close to perfect at times. The acting was perfect for this drama. I asked myself why I hadn't watched this before. The title throws you off because you have no idea what it really is about. Let's start with the stand-out actors. First of all, Ryu Deok Hwan as Han Jin Woo was unbelievably good! From the first episode to the end. His portrayal of Jin Woo was spot on perfect. Yoon Joo Hee as Kang Kyung Hee was great! At times, she drove you batty with her police decisions which made no sense to me (or maybe I watch TOO MANY police and crime dramas) but overall she did a good job. The rest of the cast was fun and acted well. Every episode was a learning experience. Keep wikipedia/google handy. You will be doing a lot of searching! Again, I cannot believe I am just watching this. Onto to season 2!
