Goddamn this show is fantastic. The characters, story, acting, action everything is just so well done. Such great production values and cinematography. I can't speak too specifically on the show since it's been a while since I've seen it but it has still strongly stuck with me. I absolutely loved how Eugene's and Koe Ae - shin's relationship developed, their romance was beautiful. All the supporting characters are strong. Eugene's confrontation of the people who wronged him as a child was great and what a great performance by Lee Byung-hun, the boy who plays him as a kid also does a wonderful job. I do remember finding the Samurai guy to be a little too edgy sometimes but he has a great story nonetheless.

As far as re watch value goes, I would watch it again but some of it is pretty sad so maybe one day.
