I’m watching this again right now. I don’t think it could get old for me. I can’t stress enough how good this show is - and not as a K Drama person, but as a fan of great television, great drama television writing, outstanding acting, and a riveting conspiracy show that plays up diplomatic tensions. This show has it all.
*Also, the show itself has dialogue in several languages - Korean, Japanese, English, Mandarin, and Hungarian!
Seriously, you should watch this show. It’s all online right here. (Warning: the first episode is a bit slower than the others, since it’s building the story, but I guaranteed you’ll be hooked at the very least by the end of episode 4, if not episode 2. ^_^)
