It seems that this is a remarkable period drama of 2003. I think this is the only period/historical drama that only focus on Police Unit and the crime they are solving. Thanks to actress Ha Ji Won that I came to try to watch this drama. So here's my own review:

Story score: 6
- Just like the crime-police investigation in modern drama, this drama is just focus on police investigation and in police unit. If you love crime and police investigation kind of drama you will find the story interesting as it shows the old style of doing an autopsy and stake out but still the same vibes in modern drama. There's also a lot of actions scene. However, in my own opinion and preference in investigation type of drama, it still lacking in some aspects such as thrill and suspense because you can easily guess what will happen next.

Acting and Casting Score: Perfect 10
- I watched this drama because of Ha Ji Won and as expected she never disappoints her fans and she deserves all the awards she gained in this drama. I always love Ha Ji Won actions scenes here. Also the other actors on the police unit are all familiar to me and I knew that they really act well. All of them deliver their lines very well.

Music Score: 4
- Singer and songs are good but it just that it is not my type of music but I love the voices of the singers.

Re-watch Value Score: 1
- Though I like to watch police investigation and action kind of drama, I wouldn't watch it again because I easily get bored. But if you're a big fan of historical, investigation drama and fan of any of the cast you might want to replay this again.

Overall Score Review: 5.5
