I watch a lot of Asian dramas. This one scores a 10 because of the unexpected plot twists. I thought about this show for weeks after I was done watching it, which does not normally happen. Any story that can stick with me like that, deserves a rating of "Brilliant", in my opinion.
As much as it pains me to give a show with Si Won and Chae Rim a score of 5, I can't give it a higher score. I had high hopes for it, since it had such a great cast, but the story fell flat. The writers failed to put enough "make cute" scenes in the show, which lead to a seemingly lack of relationship progression. I just never felt the love between the main leads, which ruined what could have been a great show.
I love the story and characters that the Hong sisters created in Hong Gil Dong. They are sometimes hilarious and sometimes noble, but always memorable. Even when they make choices you wish they wouldn't, you empathize with them and understand why they are making their choices. This story is poignant and stuck with me for several weeks after I watched it.
