I disagree with most of the other reviews, in my opinion the acting is a bit cheesy. If I were a criminal I'd want these guys investigating me because they are mostly incompetent which would be fine if this were a comedy but it's not. The story itself is interesting, and it is actually kind of funny.

As to the incompetence of these supposed police officers - the main character is knocking on doors looking for a woman. A guy answers the door and at same time the woman comes home, whereupon the guy at the door grabs a bat and starts chasing the cop and the woman. The cop and the woman split up, the guy with the bat continues after the woman... so what does the cop do, absolutely nothing and in fact looks unconcerned. On top of that a lot of the character interactions are not all that believable. Possibly they are all escapees from a mental facility living out a dream

This show has everything. Crime, drama, emotions, well structured story, great acting... Its a hidden gem and you won't be dissapointed

The beauty of this show is how little the time was spend around time travel and yet completely en-gulped by the characters and their development around the very concept of time travel. I think it is one of the very few shows nowadays that have not tried to explore the scientific reasons and get struck in those, rather a beautifully woven story of balancing ambition and personal life and deriving purpose from one another with a true happy ending.

This is a great show. What a story! I was reading the storyline and had thinking it could be a weird series. But, I'd surrender to my curiosity and got addicted to every episode. One of the best korean dramas that I've ever watched. The parallel between past and present is awesome. Park Gwang-Wo's 30 years of absence from 1986 and 2016 is the center of the show and the way that he discovers the connections between these two times and how the things are connected turn this show a good one. Good twists, good cliffhangers. If you aren't into korean dramas but want to give a chance to try, this is a good opportunity. Nice entertainment.

Great series but one question,Why the korean police officers doesn't have gun?
