This is a very nice drama for in between and genuinely something I would watch after coming home from work  during dinner. The only problem is that it does lack quite some substance to it, making the whole series a bit dull.- Cast/Acting
I really loved the acting in this drama. Everyone did an fantastic job, especially the side characters' actors were truly amazing. On that note I would like to point out that all the child actors are true little pros! Their acting skills were wonderful to watch. While I loved the acting so much in this I think some of the actors' talents were a bit wasted on the characters they played. - Story
The idea is quite simple with there being one case per episode which also spans out to the following episode. There is no true plot and if you believe we dive a bit more into - for instance - the happenings of episode 1, then the following episodes will disappoint. Certain characters have some kind of sub-plot but the main focus lies on the cases the team works on. In general I felt disconnected with the entire series and wished there would have been at least one single theme popping up once and again that would push for more character development and give the watcher some sense of anticipation or suspense.Something else that bothered me quite a lot throughout the whole drama was the extensive usage of the word profiling. As a whole the script's dialog was somewhat weird during the first few episodes, in my opinion.- OST
There is almost no OST in this drama - I'm talking about "songs" rather than instrumental background noise - which was a bit disappointing, but I liked the occasional soundtrack popping up here and there. I wish they had played it more frequently!All in all if you need something to watch in between some heart shattering dramas or if you like to chill out to some Criminal Minds in the morning during your breakfast then it surely will fulfill its duty without space for criticism. If you look for something that will make you feel like you fell through your screen and into the story and the drama itself then this is not really the right thing you are searching for, I believe.
