IU (a singer first, actress second) struggles in the first half. Her wide-eyed, bubbly portrayal feels more childlike than clever, and her crying scenes initially lack nuance. She improves significantly around episode 10, but the early criticism was valid.

The last 4-5 episodes are devastatingly good. If you love tragic, high-stakes melodrama, the ending will wreck you in the best way. It handles themes of fate, loyalty, and political betrayal with genuine weight. The Bad 1. Pacing & Editing Issues The first 6-8 episodes feel rushed and tonally uneven. Hae Soo’s modern-girl antics clash awkwardly with the palace’s brutal politics. Key character relationships develop too quickly, and some plot transitions feel abrupt—likely due to the original 20-episode plan being cut to 20 (and actually airing as 20, but the international cut is 20; some feel it needed 24).

The drama is visually stunning, with rich colors, beautiful hanboks, and atmospheric lighting. The soundtrack is legendary—songs like "For You" (EXO, CHEN, Baekhyun, XIUMIN), "Say Yes" (Loco & Punch), and Taeyeon’s haunting "All With You" will stay with you long after the credits roll.
