    Intrugied to find this show in Time Travel

    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.

    Innovative , Refreshing, Lovable , Mysteries

    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.

    Interesting but unbelievable

    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

    What a surprise

    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.

    Starts off a bit cringey and ends up truly epic

    I wrong a big long angry review after watching the first 4 or 5 episodes. It was almost unwatchable for the first 2-3 episodes -- terrible writing, cringe overacting, everyone's emotions were completely over the top, you didn't care about any of the characters, and worst of all, the main guy is just about the worst heap of steaming toxic masculinity ever to grace the silver screen. He punches and kicks everything, bullies everyone, and is one of the more unlikeable characters I've had the misfortune of watching.

    Sooooo, it turns out, it gets better. A LOT better. My wife wanted to keep watching so I stuck it out, and I'm glad we did. The first truly great episode in my opinion was #7, which is almost halfway through. But from there on out it takes many twists and turns--many of them predictable (but still satisfying) and several others which caught us by surprise.

    It probably helps to think of this show as being a bit like WandaVision, where the 1986 backstory is deliberately overacted and corny because it's (I'm guessing) mimicking the way Korean dramas/sitcoms were back in 1986. The characters, acting and writing all become significantly more mature as the 2016 timeline evolves.

    To be fair, there is still some weakness in the second half: a bit of manufactured drama from characters not telling each other critical pieces of information, poor decision-making by the police crew, and even some straight-up melodrama in the latter half, particularly in the last 3 episodes. But it's forgivable because the story is really solid. It's a very, very good story, and the first 6 episodes were more or less necessary for setting up all the complex twists and turns it takes in the second act. Oh, and the main guy becomes much more watchable after the first half, as he matures as a human being. His toxic masculinity was intentional and it gets fixed as the story unfolds.

    It's pretty obvious why there's already one remake, and it wouldn't surprise me at all to see a Korean or Hollywood remake at some point with a higher budget. It's a fairly unique story that's hard to pass up.

    There are definitely some timeline continuity issues, and they leave more questions open than they answer by the end. So don't come looking for great sci-fi here.

    But as a crime drama, this is about as solid as it gets, and my wife was bawling at the end. I might have had a sniffle or two. I'd rank this up there with Beyond Evil, Stranger/Secret Forest, and The Guest as one of the top non-romantic kdramas out there.

    Long story short: Stick with it and you'll be rewarded.
