I would describe this as a romance-centric crime thriller. Even though there is plenty of action and the hunting down of the psychopathic serial killer father is very important, ultimately this is a love story. Everything is framed through the experience of these two people who love one another deeply despite their traumatic past together. It is their relationship that is the ultimate focus of the show.

I think a viewer needs to adjust their expectations when approaching the show, because the pace can be slow and the romantic scenes long and dramatic. Well, they come off that way if you're watching exclusively for the crime element of the show. But if you can accept that really this is about love and romance that has been tainted and tested and forged through tragedy and trauma, then suddenly none of those scenes seem gratuitous or like they're dragging down the plot.

The greatest strength of the show is the cast. It features excellent actors across the board, both leads and minor actors are so emotive and layered. I was also impressed by the young actors in the flashback scenes. I have rarely enjoyed flashbacks more than in this drama, where they actually felt poignant and necessary. The leads have some of the best chemistry I've ever seen in a drama and they really suffer so much in the show that it sometimes feels a little masochistic. I can't think of a romance where the two leads have suffered more just to be together.

I think this is a great drama. Maybe not the best crime drama, but one of the best melodramatic action romances you can find. Sure the pacing isn't always perfect and there are a lot of staring scenes, but if you want to feel some intense emotions, I can't recommend highly enough. I would have cut it down to 20 episodes though, if I could have.
