I haven't watched such an intriguing crime drama ever in my life. Everything about it was so perfect. The camera angle, the style, dialogue, direction, storyline, characters, acting, music. Just perfect. I haven't feel a single point where it looks like they have inserted dialogues or scenes just to fill up an episode. Everything just happens for a reason. Every character plays a crucial role to bind the whole story. Whole time I was on the edge of my seat, whole time it feels like something is going to happen even if everything is so peaceful. You cannot even guess what would happen next, who would live who would die.
