The drama just didn't hit the spot for me. It had all these grand plans to dive deep into history and stir up political intrigue, but somehow, it lost its way in keeping things engaging. There were these bits here and there that had me hooked, they were pretty intriguing. But the storytelling was all over the place, and the characters barely had time to develop. That lack of consistency seriously put a damper on my enjoyment. I was left feeling like there was this untapped potential, they could've given us more depth and made everything gel together better. Anyway, the ending felt like it was missing some scenes before the credits; not smooth.
