I was waiting for this drama since they announced it, and I wasn't disappointed! In FACT, It became one of my all time favorite drama ever. It's such a spectacular 'humane drama', narrated as a mind-blowing psychological thriller!

Psychological Thrillers are always a treat to those who love suspense and making things out in your mind before stuff happen on screen! To top that with a heart-wrenching emotional ride isn't the most common stuff coming out these days, so I urge you please, DON'T miss THIS ONE!!!Without further ado, let's get to the actual review,

STORY: It's sublime and well refined with a DARK STORY-LINE. The main character (Dong Shik) who is a demoted detective, is suspected of killing his own sister, and the others on his team aren't totally innocent. The drama unfolds when a frightening murder happens which resembles ones happening in the span of 20 years to the past! And the young detective from Seoul vows to catch "Dong Shik" for he thinks it must be his doing and he must be the culprit of the serial murder case!

Acting/Characters: Lee Do Hyun gave an outstanding [tho very short] performance as the young Dong Shik.

Shin Ha Kyun's acting is stellar! Once again beyond words! His voice is so fitting, calming and apologetic, as if he have done the world wrong! Yet his laugh is so creepy, it's quite a thrill to look at him smirking. Jin Goo's character is usually cold and unwavering... yet with is amazing acting, he manages to make way into anyone's heart early in the drama!
All the rest of the cast are doing immensely great job, with their acting naturally flowing in, very realistic and never feel forced!
Special thanks to the lovely rookie actress, Choi Sung Eun as "Yoo Jae Yi", I can't possibly think of a better acting for her character! Not even if done by one with far more experience!

Much respect for the amazing portrayal of "Park Jeong Jae" by Choi Dae Hoon he really brought out raw feelings with his marvelous portrayal of a mentally unstable officer who has been living with so much guilt ever!

Music: The score is DRAMATIC, SUSPENSEFUL and very pleasant to listen to. The main theme grabbed my attention from the opening scene, with the beautiful blend of the violin and the percussion. and as for the songs. The song "THAT NIGHT" is the PERFECT music to give anyone chills watching this PERFECT DRAMA! It feels like a sorrowful man's screams and says letting out his long held grudges to be heard by someone in a corner... An absolute classic masterpiece that deserves best music awards for the year! I love the background musics, 'Who is the monster' 'Dong Shik Knows' 'Beyond Evil Opening Title' were absolutely beautiful! And I was getting goosebumps anytime I heard the first few seconds of 'Empty' & 'The Night' in the episode's ending minute!
Rest of the songs are all amazing, The beautiful and sad composition called "The Road" by Sunwoo Jung A is my favorite to listen to again when I miss the drama, especially if I miss Dong Shik and Ju Won's moments together!

LAST WORDS:
This drama is GREATNESS beyond WORDS! and I'm quite bad with crafty expressions, so all I can do, to give this drama justice, is ask you to start watching the first episode RIGHT AWAY, and don't let anything get your attention till you're done with the first! The rest will be history, as a matter of fact, you won't be able to stop watching! Guaranteed!

**Unless you're the type who can't stand very dark and regretful stories!**

A MUST WATCH! If you're looking for a DEEP and FASCINATING HUMANE STORY.
