I really liked this drama. It's short, only 8 episodes, but it's fun while it lasts. Since this drama is so short and each episode is truly its own entity, it's completely re-watchable. Each episode deals with a different case, and there isn't really much of a multi-episode arc. It's fun to watch Joseon-era crime solving techniques. Now, whether or not those are true to the period, I don't know, but it was good, old fashion sleuthing. A couple of cases seemed similar, but they were different enough to be entertaining. One case, though, actually gave me nightmares the night I watched because the culprit was especially creepy and calculating. There are also plenty of laughs, and a hint of romance in the drama. Not much, but it's there. The cast was great. Everything was well acted. Creepers were creepy, entitled jerks acted like douchebags, and rarely did tears seemed forced. The only song I remember (intro and outro) did start to get on my nerves around the 5th episode, though.
