Where to begin, I knew from get go this is going to be a serial killer drama. The drama starts off incredible, we as a third could see our hero aka lee sung min, a innocent kind driver is going to get in trouble as soon as he agrees to take Yeon sook aka the serial killer as a customer and drive him to destination which is four hours away.

Spoilers ahead please be warned, I cannot describe why I gave such low rating without telling any of it.

After watching many kdramas, at that point, I thought it will be typical drama, where driver will eventually find out something is wrong with the customer through clues here and there, simultaneously police will come across some victim and figure out who is the serial killer eventually, and the goal would be to catch the culprit, while our meek hero will save the day by becoming strong. I thought it would be typical plot, but it wasn't like this at all.

From the get go, the villain jokingly admits he is a serial killer to the point he seriously reveals he is indeed a killer all by himself. And he threatens our hero and tells him he needs to stow away to another country before police finds out what he did, so the hero must drive his taxi till the destination point because he doesn't know how to drive a car himself. He reveals all the details of his life, how he killed, whom he killed and everything. Which for me felt impressive. At that point I knew this take on serial killer Kdrama is very different and unique. The drama felt fresh and kept me on toes.

That's first five episodes, it felt different and incredible.

But what comes later is utter disappointment.

Just when I was thinking wow a Kdrama about a serial killer with different kind of script and not the routine writing we usually see in other dramas felt like fresh air of art. But it quickly became a typical writing style from them on.

The hero becomes damn foolish to the point because of his selfishness and dumbness alone kills three people. But I wasn't disappointed yet. Fine who is to say a hero should never be dumb. His character from the beginning of this drama has been portrayed as a weak mindset. So I can understand, even though he made stupid decision, it still felt like a decision the character would make. He wasn't totally selfish because the villain threatened him. So even three people got killed , we can understand the hero had no choice.

By the time hero and villain had finally reached the destination where the villain wanted to stow away, the serial killer reveals to hero he had killed his daughter and not only that he also shows hero the beheaded head of his daughter. The head which he hid in a trolley and made hero carry all the way by threatening him if he won't drive taxi he will kill his daughter and if he does reach the destination in time he will spare his daughter. But now we know that didn't happen. He tells hero he purposely picked his taxi for ride, because he wanted to feel the joy of knowing the hero can never win and save his daughter. He then stabs our hero and escapes.

The villain kills countless of people, and let me tell he doesn't just physically kill people, he tortures them mentally which is even more brutal than the actual act of killing. He mocks their death and all because the villain is someone who doesn't feel any emotions and he got a weird ability where he doesn't feel pain at all even if he is stabbed. Yes, he literally doesn't feel pain.

After this our hero somehow survives, a big twist comes later on who is actually involved in this killing spree, which is actually a great twist, but moving on our hero sets out to revenge. I mean come on that is the only sensible thing to do. The hero lost his daughter, that psycho murdered his daughter which even can't be called a father's worst nightmare. It is even brutal than that. Due to what happened to the daughter, the wife of hero kills herself.

The hero finally catches the villain, but you think as an audience finally our hero can avenge his daughter death, please be as good as the glory drama revenge, no no it should be even better, but hell no, the dumbass police of every Kdrama nightmare comes again. the stupid police ruins everything. Not only that, you think after all this time the hero will become strong and clever, no the villain still tortures the hero by kidnapping his daughter in law as well. He once again puts hero through all that agony and the daughter in law escapes, but hero is unaware and assumes she is dead because he knows the villain is too cruel to leave her alive, but the police interrupt, stop the hero and say "don't kill him and go to jail, you should be good person, think of the family you left".

Are you serious, dude if something like that actually happened in real life, no family would ever say stop, all that time the police ignored pleas of the victims and dismissed under context there is no proof , telling them to bring evidence, for once if the police believed the victims none of the killings would have happened, but now when the hero is getting revenge, the police became highly functional and actually follow the law all of a sudden.

All in end, there is no actually satisfaction end to this drama, the villain has a wife who gives birth to a male son, which you would think as audience won't he also turn into a serial killer when he grows up because the villain literally says his father is also similar to him. So yeah apparently it genetics. You think the villains wife, for all sins his husband has committed would have ounce of empathy and asks forgiveness and aborts the baby. Look I am all against innocent children getting effected, but god all through the series the villain asks for a baby boy because he knew his child will eventually become like him. For greater good some hard decisions to be made. The wife not only doesn't apologize, but tells our hero she will never forgive him or her husband for making her go through that. She literally says that to a man who her husband has killed his daughter and made his wife to commit to suicide.

The villain even though gets caught at the end and gets sentenced correctly, the hero is also sent to jail for seeking revenge on the villain. I mean come on dude, the writers when it came to the villain they are like let's be so creative, but when it came to hero they all became straight and arrow. The hero literally saw 10 lives of hell in while being alive.

There is no proper revenge, police are incompetent till the end, even if villain is sentenced it doesn't make any satisfactions as he lacks emotions and pain. even if you kill villain he will lose life but will not feel pain. And you send the hero aka the actual biggest victim to jail when he is been through that much torture. The only thing good about this drama is the villain is actually perfect, he is clever, sadist and is always ten steps ahead and the writing around villain itself is very creative, other than that it is no good.
