«Warning : It's gonna be a long review, has some spoilers & tho little chance this got people read on this review, I'm still gonna say it "I don't know why when this drama came out it didn't blew up like any other dramas, because THE DRAMA IS LIT!!". Please watch it if you can stand with murder, suicide, horror, mystery, psychological suspense, gore & thriller!»

Story : Full 10/10. A 'chef kiss' approved. Very intense & suspenseful. This drama won't let you rest for a bit, even there are few comedy elements in every episode, I think it was just to break the ice/suspense vibe. For someone who do believe that God, Demon, Angel are real & had paranormal experiences before, I can relate to this drama very much. Maybe that's why I felt very terrified on almost every episode (esp for Father Choi scenes, it scared me like hell). I personally viewed this drama is the leading drama for any exorcism dramas & movies out there, including Hollywood. Judge/bash me if you want, this drama was scary & sometimes too disturbing for me.

Anyway, like my headline said, the main plot of this drama is like a suspenseful version of game finding who's the real culprit, aka in this case the mainleads were finding the identity of the demon-Park Il Do. The intensity came from the drama of finding & suspecting the demon. While some episodes may convinced you on which person the demon stayed, it turned out to be wrong & there's more to the story. You'll feel like investigating with the mainleads & that's also what made this drama a masterpiece. Altho no romance this drama has executed paranormal/exorcism/demonic/horror/mystery/thriller genre successfully.

But for the record I must say that this drama actually could be shortened into 12/14 episode? There are few episodes (towards the end) that doesn't actually matters & felt repetitive. The anger dialogues between the mainleads also sometimes made me annoyed. The stubborn nature of the mainleads and some stupid decisions actually could be prevented by much more decent dialogue choice.

Cast : Absolutely perfect. The chemistry are over the top. Every cast for supporting characters are perfect, I can't imagine other casts other than this one. Their visuals & skills to be immersed with their characters are 10/10. I love seeing how in time, mainleads are bonding their friendship. Broken people with same dreadful & sad past, people who were mocked, exiled & hurt by the society. Yes their road to realize that what matters the most is each other was rocky, but I love how the ending still supports their friendship as everyone is alive & it depicts that "hope & light are always there in every darkness".

Cinematography : 10/10. It has high quality shots, pacing & it really helps to build up the tense & dreadful vibes. If you're used to watch Hollywood movies, this drama will also surely raised your standards.

Music : Absolutely perfectly chose & placed. I don't quite remember the osts, but I love how they used Korean traditional ritual music & bells effect in every Hwa Pyeong's vision scenes appeared.

Leasons To Be Learned : There'll always darkness in every person. It's depend to us whether or not we let them control us, or we defeat them by forgiving ourselves & the people that we may hate. Even if in every job & society we will always encounter with beauracracy, seniority, lies & corruption, those people will eventually got their own punishments, we just have to be patient & let the nature takes over. Lastly, appreciate every moment that you had with your family/friends/loved ones. ?

Overall conclusion : Please do watch it if you love horror movies, capable of watching thru 16 episodes of wondering, mystery & dreadful feelings. Some scenes may disturb you to the point where you felt that in real life these kind of crimes actually happened & hope seems to hard to reach. But don't worry the ride will of course worth your time & experience. This drama will also hit you differently if you also has the same believe with the presence of God, Demon, Angel, etc, even if you don't, this drama will take you to a world where possibilities of scientifically unexplained phenomenons happened. I RECOMMEND IT FOR EVERYONE!!

9,5/10???
(P.S. Would love to see reunion of the mainleads someday. Good job, production team & the casts! Will I watch it again in the future? Maybe, but for now most likely no. I have to rest my eyes, minds & soul after watching this exhausting, disturbing but exciting drama. Maybe in the next few years? I will miss their friendship (and Choi Yoon too? damn, he really is a gorgeous & hot here even if he played a priest role-forgive my thoughts, guys???)
