Yes, it happened to me after I finished Tunnel in one sitting for two days. After the last and final episode I just couldn't see myself in the mirror. Well that doesn't necessarily mean this drama is a perfection or a masterpiece. Despite having number of flaws and loopholes, it could live up to my expectations.
Although practically the concept of time traveling is superfluous and unrealistic but the integration of both past and present to solve the crime is riveting yet not extraordinary. As a viewer I appreciate the way the writers managed to maintain a cliff-hanger per episode and how one by one a particular mystery unraveled. Any sort of art/literature/entertainment can be preposterous but to make it credulous to the viewers is where the makers can show their creativity. All the credit goes to the scriptwriters who managed it pretty nicely.
In the beginning, few episodes have individual crime story which were solved meticulously by the detective team, however, the main story was there and gradually each puzzle pieces were weaved in a single thread. Though all the bits and pieces were scattered initially but the story maintained coherence till the end. Much confusion was not created with the time traveling factor. The whole drama is like a web of riddle solved rigorously. Overall the story writing was commendable but during episodes 12-16 it became excessive. For instance, if we squeeze too much lemon juice in our rice rather than giving a slight sour flavor, the whole rice would turn bitter in taste. This is what happened with Tunnel during these episodes. The flow was fascinating but due to excessive twists and turns for finding the main culprit, it kind of lost the ultimate thrilling essence in the middle part in my opinion.
One interesting thing is, they tried to depict prisoner's dilemma (a concept of game theory in economics) in a theft case but did not show it vividly. I can remember clearly this whole concept was portrayed exquisitely in the drama named "I Hear Your Voice".
On another note, indignation is inevitable upon any murderers or in general any wrong doers, nonetheless it made me ponder upon a particular thing. That is, giving a child a healthy and fine environment to grow up is extremely crucial. It is true that all the heinous murders took over negligible issues but when the culprit was a little boy from then on he had nurtured grave darkness inside him. From his early childhood the unsound experiences he gathered, later triggered him to exploit himself in a psychotic manner towards gaining aberrant pleasure. It all comes down to the upbringing, nurturing and giving a child a loving environment. Compassion can change a person at a tender age.
Moreover, I appreciate the depiction of the female character, Professor Shin Jae Yi. For goodness sake, they refrained for at least once by not showing a sassy, unintelligent and screaming woman. Shin Jae Yi is stoic but a smart, competent and educated woman who came up with brilliant clues regarding solving the cases. Loved the tough at the same time sweet bromance of Gwang Ho and Sun Jae. Love the comradeship among the fellow colleagues. As I always say Korean writers are best at portraying human relationship and emotion among each other. Hats off to the writers for that. All the casts more or less shown good acting skill though not phenomenal.
Necessary to mention that the last episode is utterly heart wrenching and is beautifully wrapped up. Especially visiting every victim's home and paying respect to each of their family was wonderfully done. This little message "Saving Life is important" is laudable.
On the other hand, background score is reasonable with the situation and I could find only one OST named Circle of Life by Kim Dong Uk. It's soft rock which gets slightly heavy at the end sounds superb.
In conclusion, this drama has the characteristics to put a viewer at the edge of their sit but comes with few flaws. If the errors and flaws can be overlooked, it's pretty interesting. I felt like I have completed reading a thriller novel. For a crime drama genre lover, I don't think it would be a bad choice for giving it a shot.

I was really curious about who the real killer
This drama is good, the beginning of the story is very interesting and until the end I was really curious about who the real killer was.The story is very interesting as it engages between the past and the future with a unique crime genre. In addition, I was also frustrated at the end of the episode because the perpetrator of the crime was really difficult to find evidence even though it was in plain sight.
As usual, I always forget about the music and ost when watching crime dramas hahahaha because I'm too focused on the content.

Best Drama For Choi Jin Hyuk
The Korean Tunnell drama is a 2017 crime drama produced by the famous OCN criminal drama company , one of Korea's most beautiful and complex dramas that talks about a complex case . The writer will have a high hand in this drama style because the way the events happen and the events are all on the writer that's why I can say the writer Lee Eun Mi was the most unique , The actors in the drama were also unique in supporting roles for the main role , all of which made a unique drama come out of it and the audience was not botheredMy Rating : 8.5/10
Very Good Drama

Soooo much better than Signal!
Same genre as Signal but this one is miles better in terms of detective work, logic and acting (although i still love Lee Je Hoon). Here the time travel is not what solves the cases. The characters are actually good detectives. Time travel is just an explanation for the existence of one character. The cases all contribute to the main plot but are just as intriguing individually. And of course the characters really choose to walk by themselves in dark alleys and fields. This is common in korean crime dramas.Was this review helpful to you?

AMAZING DRAMA!!!!
First of all, I really dont know why the reviews is below 10 because for me this drama is one of the best kdrama's ever created. This Drama makes me watched for over 1 day only that's because how amazing it is for me. For me the Acting is Super duper Amazing all of it, I want to praise the casting director because all of the actor are so amazing whenever the scenes of park kwang ho and his daughter(prof. shin jae yi/park yeon ho) who is the same age as him it feels like a father and daughter for me not as lovers i dont have any percentage I feel about them as lovers. The Ending part for me is amazing.Was this review helpful to you?

I binged this in one go. I started it and only intended to watch a couple of episodes, then I blinked my entire day was gone. It is well written, the actors were amazing. I laughed. I cried. So the story is about a detective from the eighties who is after a killer and wound up time traveling through a tunnel to the year 2016. I usually stay away from this kind of drama but someone told me it was better to watch than Signal. I did watch Signal but it has no ending.
Anyway, the storyline was amazing. Even though I guessed who the actual killer was around ep ten. It's still worth the watch.
Jin-Hyuk, I cannot believe I watched this entire thing without recognizing him! I'm a horrible fan girl!!! He was in Rugal which I love!
Hyun-Min is the only reason why I'll be watching MY HOLO LOVE. He is an amazing actor. His emotions were perfect and had me glued to my screen.
This is definitely one I'll be rewatching. I enjoyed it thoroughly.

It’s a show where all the characters go out of their way to be unfriendly. So when they are even mildly civil, it’s such a great improvement that the rest of the cast are shocked.
“You didn’t hang up. I thought you would.”
Kwang Ho
Choi Jin Hyuk as our hero is a good character to portray the rough and read 80s cop who has straight values.
Sun Jae
Sun Jae is the most hostile out of the lot of them but he gravitates towards Professor Shin because she is just as isolating as he is.
Professor Shin
Professor Shin is a quiet and dark individual who doesn’t have much to say unless it’s important. Then she spits it out and shuts up again.
“I thought I’d handle it well no matter what happens.”
The show demonstrates how despite her experience and dark nature, she is human and the actress portrays her quiet vulnerability with underlying strength.
Sung Shik
I found it very cute that the chief used to be Kwang Ho’s maknae and they resume that same relationship 30 years into the future despite Sung Shik obviously being older than Kwang Ho now in the present.
Yeon Sook
Kwang Ho’s wife is a dignified and composed cop’s wife. She is beautiful and gentle. The actress does a wonderful job of smiling at Choi Jin Hyuk like she is so freakin’ proud of him and thinks he’s the greatest thing alive.
The last couple of episodes really lose the plot with originally smart characters fumbling around just to fill the episodes. But the ending of the ending is filled with all the feelings. I loved it.

Definitely not a 10/10 but still great
As I was finishing up the series last night, I thought I’d read what other people thought about the series and...well, I do agree with a lot of them. I just want to say I did see “Signal” first so this is definitely a bit of a downgrade except possibly for the acting.The acting is amazing and the chemistry between the main characters is great. Choi’s emotions just pour out and it’s heart-wrenching especially by the end. It’s great just watching the actors and their characters interact and their relationships get stronger as time goes on and I love that.
The story. As a whole I liked it but it definitely suffers from pacing and a few plot holes. By the end I wasn’t as invested as I was with Signal, but at least Tunnel actually has a closed ending. Yes, I would have liked to see what the real future would have been like, but I’ll take the ending we got. Anyway the story was definitely enjoyable and most of the complaints I had have been brought up by other members here so I’ll spare who ever is willing to read this. A solid 7/10. If it cut down on beating around the bush, I’d gladly have given it at least an 8.
I’m a sucker for time-travel shows and Mystery but I’ve binged two similar shows in a week and I’m getting fatigue so I think it’s time to watch something lighter before going for one more Fantasy/Crime drama.

The end of the drama
Well, lets leave behind the fact that the drama was tedious in some parts because they want 16 episodes 1 hour each, just for 1 serial killer.I didn't like the end. First, they caught the killer in the present so he had to catch him again in the past(at least he knew the way). Secondly, I was happy he made it to go back to his wife and child but what about the others? The rookie from the past didn't become chief? Kim Seon Jae did not become detective and did not meet Shin Jae Yi? I mean everything changed and he have no idea how. At least they could have shown everyone 30 years later and what they were doing. This would be the perfect end.
Anyway, I really enjoyed this drama but if the end of a movie or drama doesn't satisfy me....I mean that's what the whole thing was about. Dont screw it in the end!
The reason i put 8 as rating and not higher is because i don't think it deserves 8.7(current rating). If you wanna watch something simiral with fantasy then watch "He is phycometric"(maybe this will make you cry a little bit more but defenitely worth watching much more)
