This was a very fast but good drama. I think they should have made it longer and actually focus on the characters relationships develop with their other counter part. All the episodes combined make up a full length of a movie.
This is a very long and dull crime drama. It doesn't get really interesting and into the plot till around episode 20. I like the relationship between the characters, but I think they could have done better with the story line.
