This second season is not quite as good as the first one but still it better than others. The cast and acting is quite amazing, the only thing this season floop a little bit is just in story. This is a must watch for anyone interested in police and investigation type series.
One of the things this drama is missing Shin Hye Sun, it is really a shame that her character died in the first season. Her acting along side with the two Main leads would have been an amazing trio actors.
Hope they continued with a 3rd season involving a little bit more of chaebol families and probably adding a little bit of romance between the leads, because is a little bit frustating they been involve is a "some" type of relationship. I'm saying this because only two females were able to make Shi Mok express some emotions, one is already dead and the other really cares a lot of him.
