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

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.

Family of three adults and we all watched together. After one episode we were hooked! Watched one or two episodes every day and sad that we have completed our journey. We loved the characters and story. We have watched many many TV shows and movies this past year and this has to be our favorite, by far.

After a very long time I am penning down reviews for any series . Till date I have watched almost 1000+ movies & 50 + Series across all languages . Specifically Hollywood .

I must say Korean Cinema is moving to next level at a very good speed.

This series is so refreshing , innovative, and nicely crafted. Be it acting , screenplay , Direction , story all at it best . Great Job done by team of the 'Tunnel' . I would suggest everyone just give a try and from team come up with Season 2 with more spine chilling mystery and Innovation.

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