Almost didn't watch this based on the reviews on this page but so glad I did, it's an excellent piece of Shakespearean drama. The performances are excellent, Piggot-Smith is the standout, and it's satisfyingly short and efficient in its storytelling.
As far as I can tell many of the criticisms either come from offended monarchists or people who didn't like the blank verse dialogue and unrealistic plot. Although I can see why these would be issues for some people, I think they are inherent to it's pho-Shakespearean nature, it's not pretending to be an accurate and earnest take on the monarchy, it merely uses them it as setting and the Royals as very loosely based caricatures.
Go in expecting Shakespeare in a modern context, not a realistic drama about the monarchy.
