    Brilliant. Watch it!
  • May 28, 2021
    Love this one! TN is a queen! Taut, twisting, and clever, this season kills it
  • May 20, 2021
    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.
  • Jan 01, 2021
    Unrelenting start to finish. Ties into first three seasons so make sure to watch them first. Fantastic
  • Aug 10, 2020
    Another gripping story from Line of Duty. Maybe not as exhilarating as previous seasons, but does not disappoint.
  • May 25, 2020
    You just know the bad guy is going to get away with their deed, biting fingernails. Yelling at the screen.

    I watched up to Season 4 but I won't watch more. Its very well written and acted. Unfortunately the BBC Diversity Police got their clutches on what could have been a great drama. If you'd never been to the UK and watched this you'd think A. that 30% or more of the UK population is Black, which it isn't (Its less than 10%) and B. Most of the most physically demanding police jobs in the UK are done by Women, which is not the case by a very long way. The finale of Season 4 was farcical and a big let down after hours spent watching the build-up!. As a Brit I can't stand to watch any more of this grossly misrepresented view of British society.

    The core characters continue to develop in this excellent series.
  • Jun 15, 2019
    A bit disappointing compared to the first three series, I didn't fnd the performances beleiveable. Maybe the Director/Producer had been briefed to make it really fast paced. Maybe they felt something to prove because Thandi Newton was on board. There was no space for the characters or story to breathe. Disappointed.

    Gripping throughout as always.
