When I finally discovered Korean dramas, I completely gave up Hollywood, and since then have watched over 200 k-dramas and movies. While there are many good ones, there are only a couple which are at the absolute top of my list. It's almost impossible to compare modern and historical dramas, but among (mostly) modern dramas, this one is at the top of my list. It has everything one could want in a drama. It's counterpart at the top of my historical drama list is Empress Ki. These dramas star two of Korea's top actresses, who demonstrate convincingly why they have that status.
