I just finished Reply 1988, and it ripped my heart out. I dare to say, it may have been even better than Reply 1997. The music... I've been listening to so many Immortal song 2 shows, that three of the tracks from Reply 1988 OST I knew by heart even before watching the show. This has never happened to me before.
Seriously heart-wrenching drama. And Kim Feel's rendition of "Youth" is superb. How can such a young man in the colour of his voice have a 90-year old tired man??
