It seems that some reviewers are basing their opinions on their political biases, rather than on the quality of the production, the plot or the acting. I binge-watched all 4 episodes. The performance of the main cast was convincing and the storyline wasn't too far-fetched to be believable. There were some minor weaknesses, such as the Prime Minister having no facial expressions due to a Botox overdrive (even though McCrory played the part well), but overall it's pretty good. The ending opens the possibility of a second series.
