I have only seen Hwang Jin-Yi from this list. I think because I have seen it after watching the drama, I was disappointed, but it is a good story and wonderful cast. Will look for Legend of Ginko. Sounds intersting and of course, I love Choi Jin-Shil.
The Firstborn, really gave us a slice of history in Korea. We saw how fashion changed over the years, and we saw the political environment. Acting was far superior to the leads in Golden Rainbow (except for Jung Il-Woo who is always phenomenal), which was a story removed from it's time, with no effort to show the changing times.
