I really liked this series for the following reasons. 1) The acting is very good, and the child actors are not only adorable but they are also talented. 2) Each murder the detectives investigate is interesting, and involves a different part of society. There are murders were soldiers, monks, mixed martial arts fighters, and various other groups and professions are involved. 3) I was never able to figure out where an investigation would lead the detectives, and who was ultimately the guilty person. 4) While there is an ongoing subplot, it doesn't distract from the various investigations. 5) While I would have liked to see the last season of the series end a little differently. I was okay with the final episode. 6) This series that spans a good number of seasons, remains consistently good to the end. Many series don't sustain the original good quality of the first season. It is my impression that directors and writers leave series after the first or second season. This can be true of the original cast members also. That causes a change in a series, that is seldom good. I'm really pleased that this series had as many seasons as it did. I will miss it.
