I haven't yet seen this week's ep but last week's ep 4 was brilliant. The large amount of time devoted to Jang Il's fear and almost a sociopath way of overcoming it (practicing his 'surprised face at friend's murder,' saying that he'll have everything he wants but will feel guilty for Sun Woo's death so that sound be enough) was wonderful - it felt organic to the story and fleshed out JI's character (even if that meant I know loathe every second I see him).
I am going to miss Lee Hyun Woo who did a marvelous job and I hope this is the start of a great career for him. But UTW took over as grown-up Sun Woo almost seamlessly - I can believe him the continuation of his teenage self - the hot-headedness, the fear under the bravado, the temper, the grit.
I still hate grown-up Jang Il but watching his suffer the torments of the damned as he tries to wriggle out of the evil act of his past will be fascinating.
Bring it on, drama!
