I'm only one episode in. So far, the characterisation is good. The production values impressive and the direction stellar. Alas, already the immersion into the 16th century setting is stifled by 21st century narratives.
I'm personally not a British person. Yet, I can't help but feel insulted on behalf of the real historical people of the time period in England.
When I watch a "historical drama", as a viewer with an interest in history, I want immersion. It's a sad indictment of modern society when historical TV productions feel obligated to be all inclusive in the name of progressive politics.
The story itself is very intriguing, but the show as a whole feels disingenuous and far removed from the time period. There are dual narratives at play. One is set in the 16th century and the other is set firmly in the 21st and it's difficult to separate one from the other.
If you don't require immersion you'll probably enjoy the series. However, I personally find it difficult to suspend belief enough to envision that so many people in 16th England were of Asian and sub-Saharan African descent.
This is just an honest opinion of someone who has no political agenda or biases whatsoever. I like historical dramas. Unfortunately, this historical/fantasy hybrid is not something I can invest in.
