It's hard for me to wrap my head around what I have just seen and what exactly I was supposed to get out of watching this show.

The idea behind the story and the issues presented were extremely interesting, but at some point I had a feeling as if too much was happening in too quick of a pace with too much of over the top action. It moved from dark psychological school thriller to dark action flick? I felt like instead of giving us a cohesive story, the writer wanted to outdo himself by writing more extra and shocking scenes and plot lines one after the other.

The biggest problem I had was the fact some characters did not feel grounded in the story. Gi Tae and Hae Gyung were the two that stood out for me the most and I failed to understand them and their motivations. The change from school bully and teen delinquent to whatever Gi Tae became at the end seems random. Hae Gyung's introduction to the plot and her obsession over the case were also questionable.

On the bright side (if you can even call it that), all the characters were bad people, morally gray at best. While it was refreshing and interesting to watch a show where there are no heroes and no one to truly root for, it can also make you feel depressed and overwhelmed.

Some plot lines that were introduced led nowhere and were mere devices to push the characters into a corner, hence never got a proper closure, like the whole side story of Ji Soo's father or the guy Gyuri's parents worked with, that clearly was interested in her.

But then, truth to be told, the whole drama had no closure and clear cut ending. The last few scenes literally presented more new questions than answers. With that heavy of a story, leaving viewers without proper explanation may be risky. I myself feel as if my brain was just turned into pudding and any attempts to understand the ending or certain plots would lead me to more confusion and frustration.

The acting was quite a masterpiece. All the lead actors aced their roles, which were not easy to pull off. To sell a story, performers often use their own experience as a reference, but with crazy stuff happening in this show, it's hard to even imagine what the characters would feel, not to mention act it out. On other technicalities, it was beautifully shot. While the pictures were gruesome at times, I still enjoyed the camera work, use of colors and shadows and the transitions between the scenes.

Overall, not a drama for everyone. Gore, death, pain, suffering, abuse, mental and physical struggle - it's a perfect combination to get yourself in a depressive state or murderous mood. I took my sweet time watching this drama, not being able to watch more than one episode per day. But then binged watched the last three just to get it over with. While, in some weird way, I enjoyed the process of watching, I also feel exhausted and happy it's finally over.
