The critics are right. Bland acting, historical inaccuracy and cultural appropriation of Chinese elements everywhere. This deserved the cancellation. The plot is totally nonsense, with a bland and fake representation.
Not worth wasting time to watch this.
For someone not knowing the matters, ignorance is not an excuse. Throughout 2 episodes, there is more Chinese inflence than Joseon period. Bad cinematography and color shaping, fetish of children and so on.
I am not surprised about the flop and the cancellation.
