The first half of this drama is so ridiculously bad. And the second half is ridiculously good. The things that brothers will do to protect each other. *sob. I think the second half gets better because Hyeon starts talking like a normal person instead of a god-like character who is better than everyone else. Also the mind games between the gents really starts and I always appreciate a well-timed stand off. It's a nice change to have males being platonically possessive over each other rather than fighting over a girl. As for the theme of nature vs. nurture, I wasn't so impressed. But the other theme of craving bro-ship from the heart vs. the mind was really good. There are so many intense conversations where they are talking abstractly about mundane things but everyone in the room knows that they're talking about something else entirely different. I appreciate those moments a lot. Even Ji An gets in on it when she finds out. Hyeon “Please stop saying psychopathic things.” This is my first Seo In Guk drama and I wasn't quite sold on his looks but he became more handsome as the drama went along. I'm not sure if I've ever disliked a personality as much as this guy. I think he'd be an okay character if there wasn't a pathetic Ji An for him to bully and act all superior like too. It's way too over the top. I wasn't quite in the mood for his stereotypical brand of arrogance especially after seeing Healer's classy condescension. But I stayed on because I wanted to see how smart he really was and see how his talent and his tale unfolded. Those kid flashbacks sucked me right in. I liked the idea of him having a Sherlock Holmes memory and intuition but him having amnesia in some areas of his life. He is a neat freak. His best moments are concerning his brother. Those are intense. Ji An Ji An is the type of heroine I hate. She's clumsy, slow on the uptake, and presumptuous. She embarrasses herself constantly, can't string a sentence and is put in a badass job position for her to disgrace. But I believe in Kdramas and their character development so I persevered. She's not a very good personality for Hyeon to bounce off. Her pluses include that she works hard, that she can shoot a gun and she gets less annoying as the drama goes on. There's a pretty good spoiler about Ji An that comes out in Episode 5. Later on she gets some moments to shine which is great. Romance Basically every thing and everyone in this drama had chemistry except for the romance. As per usual, Hyeon acts like he's so much better than Ji An and looks at her like she is a dirt on his shoe. They had better chemistry as forensic partners or in a student/teacher dynamic. The way they could understand each other well without using words on the job was pretty cool. For most of the drama it's all about Hyeon and his problems and why his poor manners gets to be excused because of his miserable life. I liked it towards the end of the drama where he starts to show compassion for Ji An and what she has experienced because of a serial killer. Attorney Jeung His baby face....gaah! He was definitely one of the motivating factors of keeping up with this drama. The way he so deftly portrayed sinister evil and heart-breaking sadness at the same time was pretty amazing. Investigation Team I liked the dynamic of this bunch. They made me smile with their enthusiasm. They're a quirky group and there's just something about them that entertained me. They are like a rag-tag crowd of siblings. They all have their individual “roles” (the analytical one, the grump, the braggart, etc.) but nobody is a stereotype. The most grumpy one is also the most compassionate. I like that. They bicker, fight, and wax philosophical about the criminals that they catch. And they're noisy. I loved them. Also, while all of them are not that bright, they're always ready to throw down.
