[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

Matthew P. @mattyp1977 Apr 6 Such a great series from the off. See more A.L.Jude P @judebd Nov 26 Great Brit series second to nothing. See more John S @JohnSmithReviews 05/18/2025 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 02/13/2025 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 10/24/2024 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 Anton T @RT55511123 07/30/2024 BBC tend to know how to do dramas and this is no different. An explosive start sets the precedent, and thus begin a chain of events that ripple throughout the entire series. The beginnings of Arnott, Fleming and Hastings as a trio pulls you in their direction without you realising, and you could easily be seen disliking them at the start for going after Gates but then by the end you are sold on their mission. Lennie James as Gates, his portrayal as a genuine family man who's past mistakes catch upto him and drown him slowly is brilliant, the ideal broken antihero. Yes it's fiction and yes it's dramatised for effect, there's chases and torture scenes which perhaps happen too often for a police drama about corruption but the exploration of the deep and dark recesses of the criminal underworld gives serious thought as to how a small mistake can end up with someone paying the ultimate price. Must watch and thoroughly engaging. See more Read all reviews
