      Anita F Love this series. One of the best I've ever watched. Rated 5 out of 5 stars 07/29/23 Full Review Audience Member 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. Rated 4.5 out of 5 stars 01/09/23 Full Review Audience Member Brilliant. Watch it! Rated 5 out of 5 stars 01/09/23 Full Review Audience Member Love this one! TN is a queen! Taut, twisting, and clever, this season kills it Rated 5 out of 5 stars 01/09/23 Full Review Audience Member I was scared to watch series 4 as didn't think anything could top series 3. Didn't think 4 was as good. The storyline seemed too unrealistic. Rated 3 out of 5 stars 01/09/23 Full Review Audience Member Unrelenting start to finish. Ties into first three seasons so make sure to watch them first. Fantastic Rated 5 out of 5 stars 01/09/23 Full Review Read all reviews Post a rating

      Andrew Billen Times (UK) Much as I love the cast and the dialogue, this season's plotting verges on the farcical. Rated: 3/5 Jan 3, 2018 Full Review Phil Harrison Guardian What is beyond dispute is that Thandie Newton's DCI Roz Huntley was a startling creation, equal parts brittle anxiety and relentless, shameless calculation. Dec 18, 2017 Full Review Deborah Ross Daily Mail (UK) The finale was phenomenally exciting. Rated: 5/5 Aug 30, 2017 Full Review David Zurawik Baltimore Sun 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. Dec 19, 2019 Full Review Keith Watson Metro Newspaper (UK) ...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. Rated: 5/5 May 20, 2019 Full Review Cameron K. McEwan Digital Spy The series was perhaps a touch more over-the-top than previous ones, but it was still bloody brilliant television, leaving viewers with more unanswered questions than ever before.
