The plot is thick and full of twists and turns. The actor who plays president is so good. This show exhibits extremely clever writing, loads of action, and tear-jerking moments. My favorite character in the U.S. version is Kimble Hookstraten. The Korean equivalent of her is the leader of the opposition party (Korea has a different government structure) and she is a main character with so many layers. What a treat! It was tough having to read subtitles while trying to appreciate the acting but you eventually get used it.
