Much as I love the cast and the dialogue, this season's plotting verges on the farcical. Go to Full Review
Phil Harrison Guardian 12/18/2017
What is beyond dispute is that Thandie Newton's DCI Roz Huntley was a startling creation, equal parts brittle anxiety and relentless, shameless calculation. Go to Full Review

David Zurawik Baltimore Sun 12/19/2019
The plots are wonderfully dizzying. But what I love is the great moral center to the series provided by Hastings, a quirky, sometimes cranky, hard to love, but easy to admire leader of this beleaguered anti-corruption team. Go to Full Review
Keith Watson Metro Newspaper (UK) 05/20/2019
5/5
...Line Of Duty takes the familiar police procedural drama and turns it on its head. There are layers upon layers at work. So when you think a line of inquiry is putting one individual in the frame, a different suspect emerges. Go to Full Review

Alain E @AlainE Dec 7 So many series deliver a strong first season and then fail to sustain the quality. Maybe because this takes a couple years for the next sequence, it remains very watchable, building characters that appear realistic. The script avoids the simplest solutions. Bad characters are multidimensional bad, but then they exhibit unexpected adherence to moral values. For example, the corrupt Roz of this season doesn’t hesitate to send her own husband to prison, accusing him for the crimes she committed, but she draws the line in having sex with her supervisor, in exchange for crucial information that he provides her with. On Prime, which doesn’t include all the seasons. See more don c @Donald290 Sep 29 Really enjoyed previous seasons, but this one was so intent on being clever it strayed into the territory of the ridiculous. See more Ma'ark T @RT57514104 Jul 24 Line of Duty Season 4 is just as good as the frist 3 seasons if not better. I like how it keeps tying back to previous season but not too much. I think I also just like the idea of corrupt police being caught. See more Anita F @RT48915707 07/29/2023 Love this series. One of the best I've ever watched. See more John O @ThreeRivers 07/14/2022 Spoilers: They blew the title, as this was so thoroughly British, it was all about words, with long stretches of nothing but words in an interview room. Call it: Perverting the Course of Justice. What justice system besides the Brits has such a serious criminal charge? Perverting the course of justice? Uh, could you be a little more specific? No, mate, cheers, we got it covered. Yeah, you got EVERYTHING covered. You all right? I love the words they use, different than what we Yanks use across the pond. It's as if they are all always challenging each other to get the words right. Show Mummy you are doing the right thing, Ma'am. Are you a DC or a DS or a DCI, and get it right, already? Like their tennis. Is it a game point or set point or match point or championship point? If you don't get it right, dammit, you just aren't trying hard enough, you wanker! The Brits seem almost gentle, authority loving, even formal and "proper." And AC-12 cleans up the good guys who are really bad guys because that's the way they do it, for queen and country! And, really, God bless 'em, they don't carry guns without 14 layers of permission to even get the gun then return it (learn something, U.S. Senate!). Love Vicky McClure, big eyes, big heart, helps her sell betrayal, and Compston, he polished up the handle so carefully, and Dunbar, but we won't go down without a fight, are good, and Keeley, true meets false, and Polly, loyalty shmoyalty, too, and Thandie makes acting almost ethereally transcendent. The writer Mercurio has to give us 18 twists and turns or he just isn't giving it a proper turn at excellence and is just another wanker, mate! Sir! We'll overlook the traditional the sun never sets on the British empire angle, which ain't so proper, mate, what with boot heels on Irish necks and those of all manner of woggs in the colonies and such. This is cops making sure cops are cops and not robbers. Pip pip, mates! Cheers! Writing uneven but good enough, and better than a lot of TV. Soap angles, who's shaggin whom (not who!), mate, were fine because not overdone. Trust Mummy, mate, but keep an eye on everyone else, DS Fleming! Cheers! So, this is not bollocks, Ma'am ... as you were. See more Biff H @RT78223616 10/12/2021 Brilliant. Watch it! See more Read all reviews
