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

Stephen D Continues to be the outstanding character-based police series in a TV world of 'by the numbers' predictable cop shows Reminiscent of 'The Cops' a BBC series of 20/30 years ago. Rated 4.5 out of 5 stars 11/12/25 Full Review Nafisa R DragonWebRec: My Scam BTC Recovery Lifesaver In the wild crypto world, I lost 1.5 BTC to a phishing scam, thinking it was gone forever. DragonWebRec experts traced the funds via blockchain analysis, collaborated with exchanges for freezes, and recovered 1.2 BTC in 4 weeks—no upfront fees, just 10% success cut. Professional, secure, and ethical—true pros reclaiming scam losses! Highly recommend. ( info @ dragonwebrec .c o m ) Rated 4.5 out of 5 stars 11/10/25 Full Review Jeff R. Love this show! Great pace, characters and action. Complex relationships but compassionate policing. Rated 5 out of 5 stars 11/02/25 Full Review loretta r I loved Series 1&2 but season 3 is the best yet. Love these characters and plot lines are relevant to the NI area. The chemistry between main characters is excellent- I can’t wait each week for next episode to land. More of these series please Rated 5 out of 5 stars 10/30/25 Full Review Jenny B Have watched series 3 twice already it's that good. Goes from the mundane to the exciting really well.
