The storyline is really great. The political & moral issues presented has given me lots of heart ache & head ache but every scene & every episode is just too incredibly well-made to pass up. Though there were scenes that felt like it was prolonged/dragged & could've been shortened but it's well-made & well-acted & those scenes fits perfectly with the subject & the plot so I can't really complain about it. Truly great plot...got me hooked that I binged watch it. The casts are really amazing as well & as always, Jung Il Woo has taken over my heart again. He's really incredible. Directors/producers can never be wrong casting him in a historical drama...royalty suits him.
