Alessandra Stanley New York Times Oct 17, 2018
[It has] an excellent cast, skillful writing and a knack for making an exotic, unfamiliar world seem like the viewer's second home. Go to Full Review

EDWARD M @Eddit123 Aug 8, 2026 Beyond excellent. It is like putting a 10 thousand piece puzzle together of the Mona Lisa.... See more Matthew P. @mattyp1977 Apr 6, 2026 Such a great series from the off. See more A.L.Jude P @judebd Nov 26, 2025 Great Brit series second to nothing. See more John S @JohnSmithReviews May 18, 2025 Decent enough pace to the series and plot as it builds though the characters are just feeble caricatures. When it starts to reach a climax it just ends with a damp squib and gives up completely. Thoroughly feeble conclusion. See more JFO T @RT69617081 Feb 13, 2025 Disclaimer: I watched the first season. I couldn't watch more... The ideas in the plot are good! But the whole thing is written by people that does not understand how things work... The characters and dialogs are really bad. They are caricatures of good / bad / stupid archetypes, over the top for a show that wants to be serious. The characters are as credible as the first excuse of a kid for why they didn't do their homework / chores. If you watch light things without paying much attention this can work. A lot happens each episode and it could be entertaining. If you enjoy coherent characters and good dialogs, avoid this. See more Prabhudas K @Pdkamath Oct 24, 2024 Finally a great series, Loved every episode. Perfectly paced, wonderful casting, great acting. Congratulations producers, you nailed it!! Love to see many more like this. See more Read all reviews
