Ed Power Daily Telegraph (UK) Series three still has lots of what viewers love about the show... In that respect it remains a superior thriller – but one surely now in danger of becoming just another generic UK cop caper, with a side-serving of Dublin gangland sensationalism. Sep 30, 2025 Full Review Jack Seale Guardian As viewers have got to know and like these people, the soppier character work has started to push the tough sectarian dynamics aside. Rated: 3/5 Sep 30, 2025 Full Review Carol Midgley The Times (UK) The lives of the officers feel real. Yes, it starts slowly, but this long-form storytelling is always worth the investment. Rated: 4/5 Sep 29, 2025 Full Review Alison Rowat The Herald (Scotland) It is early days, but I am going to come right out and say it: Blue Lights, the Belfast-set police procedural, is better than Line of Duty. Oct 9, 2025 Full Review Gerard Gilbert iNews.co.uk Blue Lights might settle into being just another standard police procedural. In the meantime, however, it remains the best cop show on British TV. Rated: 4/5 Oct 1, 2025 Full Review Christopher Stevens Daily Mail (UK) All these romances are starting to give me what Love Island calls 'the ick'. Rated: 3/5 Sep 29, 2025 Full Review Read all reviews

Jenny B Have watched series 3 twice already it's that good. Goes from the mundane to the exciting really well. Rated 5 out of 5 stars 10/28/25 Full Review Marc P Season 3 is so good. All three seasons are excellent. Rated 5 out of 5 stars 10/27/25 Full Review Andrei D The escalation at the end feels a little much given the approach so far but the acting is strong and the Belfast vibes are good Rated 3.5 out of 5 stars 10/26/25 Full Review Julian J I don't get it. The storyline is pretty standard for a cop show and somehow it just exceeds all your expectations. It has drama, deep quotes, romance, grief, history, action, all in one. Rated 5 out of 5 stars 10/25/25 Full Review Dma D. Goog movie, recommended1111 Rated 4.5 out of 5 stars 10/22/25 Full Review David G That good I binge watched all episodes and went to bed at 3am. Its really so authentic and plausible. The city, the plot and characters are brilliantly drawn and acted out superbly. Rated 5 out of 5 stars 10/18/25 Full Review Read all reviews
