Kathryn VanArendonk New York Magazine/Vulture 5d
Blue Lights has strong performances bursting out of every cop car and uniform locker, Brooke is the quiet lead of the show’s ensemble with Grace’s outsider status keeping her aware of and alive to the frustration of these long-entrenched criminal actors.

Blue Lights definitely wants to be the Belfast equivalent of The Wire. It never quite gets there, but there's also no shame in not living up to one of the greatest TV dramas ever made. Go to Full Review Ed Power Daily Telegraph (UK) Sep 30
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.

While it once again balances the private and professional lives of its officers, this go-around feels more painfully personal. Go to Full Review Alison Rowat The Herald (Scotland) Oct 9
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. Go to Full Review Gerard Gilbert iNews.co.uk Oct 1
4/5
Blue Lights might settle into being just another standard police procedural. In the meantime, however, it remains the best cop show on British TV. Go to Full Review Read all reviews

Rich C 1d The best show on any network. See more Ittay1 S 2d Outstandingly excellent on all counts! I love it when you feel the creators love their characters! Even most of the bad guys have a touching, loveable side. Line of Duty excellence + so much human warmth and authenticity = what else could I hope for? See more Rudy C Nov 25 Great writing, great acting, great characters. Wish there were more on streaming as good as this one. See more Cindy M Nov 22 Human stories written and acted so well that watching Blue Lights puts the viewer right there with the characters. More than watching, viewers experience and feel the situations. Blue Lights is the gold standard to which all detective and police procedurals should be held. See more Joshua H Nov 19 The best series so far! Strong developd characters, gripping story line, and an emotional roller coaster! See more Patrick O Nov 19 Undoubtedly the best Police drama since lockdown. Series 3 is so emotional you may shed a tear. Outstanding. See more Read all reviews
