Cons:
1. Too many names and terms to remember. You gotta take a note.
2. Too many faces to distinguish. The villains look similar at the beginning :(
3. Complicated political moves that I forgot who betrayed who. Which one is on one's side.
4. The subtitles can't cover all the captions' translation. So, you gotta hang on it. Eventually, the terms will get their translation later.

Pros:
1. The visual graphic is so woowww.
2. Top-tier moral story.
3. The adventure vibe is so strong that you can feel it in front of your device.
4. This series creates its own language. It adds the vibe mentioned above.
5. The most beautiful Kim Ji Won you can watch in this series.
