Overall this was a good drama. It didn't have much action, the episodes all had a rather similar scheme and there weren't many surprises. The cases were great and so many details were planned to make them solve the locked room mysteries. Often the suspects were obvious, but the way they realized it wasn't. The music was good, it matched the drama perfectly. The acting was good, too. There weren't many dramatical or tearful / painful scenes to play, but everyone stayed in character and did a good job. The story itself was okay. I was more fond of the characters because there wasn't much development in the story, it pretty much stayed the same. I was completely disappointed by the ending, but it's not going to change my score. I'm hoping for a sequel or special now, though I think it's unlikely. You should try this drama anyway and give it a chance. ;)
