The BBC has shared a first look at the new series of the police drama Blue Lights, which fans have called "the best cop show."

Return of Cast and New Episodes

The Belfast-set series, which has become a huge success since it started in 2023, will return for a fourth run. Images show Siân Brooke, Martin McCann, Katherine Devlin and Nathan Braniff back in uniform. Game of Thrones' Richard Dormer also returns as Gerry Cliff, alongside Hannah McClean as solicitor Jen Robinson and Jonathan Harden as disgraced former Inspector Jonty, in an episode "that will answer important questions from the past."

Fan Reactions and Praise

Fans have eagerly awaited the new episodes after declaring the first three series "excellent" and "outstanding." One IMDb comment called it "entertainment at its best." An ex-cop remarked: "As an ex-cop, I'm so sick of US made cookie cutter police shows. Blue Lights in my opinion is bang on what it's like to be cop." Another viewer wrote: "Brilliant acting, directing, production - award winning drama all round." On Reddit, a fan said: "If you haven't watched Blue Lights yet, you're missing out on one of the best shows in years. This is a must watch show, one of the best of the 2020s and will one day be a classic." Another called it "a masterpiece of a show."
