It have a very cool concept of time traveling to solve a serial murder case, but I think they didn’t fully utilize the time travel element. It feels more like your standard crime drama instead of a time travel crime drama.

If you’re going to make a time travel drama then you have to include the out of time person element in the drama. You need to show some kind of adjustment period to the new time. There are almost none other than a few line here and there. They spend several episode being crime of the week type to introduce the character and how they get along. They should also have used these episodes to show us how the main character adjusting to all the new rule in this modern time. How he get to know the current crime scene procedure, how to use the computer, what new science used to find suspect, and all that stuff. Unfortunately they take the easy route, by just mentioning a few line in every episodes, which is a lame thing to do.

If they are not going to use the fish out of water aspect of time travel than they shouldn’t bother making this a time travel drama. They should just stick to standard crime drama, which is good enough, but it could be so much more.

The main case that needs to be solve is interesting and quite clever, there are quite a few twist that makes this an interesting case. However I didn’t see the point of why there’s a need to time travel to solve this drama. It could be just your standard crime drama and it would still be interesting, especially if they delve deeper into the victims, which they didn’t do here, since it’s supposed to happened 30 years ago. It could be an even more interesting crime story instead of this half baked time travel story.

The acting is really good, everyone portray their roles very well. My favorite is the second lead, Yoon Hyun Min playing as Kim Seon Jae. He give a really good performance as a misunderstood, arrogant and smart detective. There are layer and depth to his character.

I wish the main lead, Park Kwang Ho played by Choi Jin Hyuk, give off more out of time element. He didn’t look like a person out of time at all, everything workout too perfectly, but he did an awesome job looking like a father and older brother to the other character that I would not mention. The other casts also give good performances.

The music is okay, no song that really grab my attention. The costume and set design of the old time is not old looking enough in my opinion, especially considering it’s supposed to be in 1986. The clothing and hair style looks more like a 90’s fashion, in my opinion.

Overall this is an enjoyable crime drama, but not so good time travel drama. I probably would watch it again in the future, but not sure. I would recommend this to those who loves crime drama but I would not recommend it to those looking for time travel, lost in time drama.
