Blue Lights creators say series 3 is 'darkest' and 'most ambitious' so far"It's always important in every season to shift up the show and make it feel different - Belfast is like a patchwork quilt of stories"View 4 Images Blue Lights series 3 (Image: BBC/Two Cities Television/Matthias Clamer)Blue Lights is finally back on our screens next week for the highly anticipated third series and the creators have said that this is their "most ambitious series yet". ‌Speaking at a Blue Lights set visit back in March, Adam and Declan shared a taste of what is to come for our young officers two years into the job, why they think Blue Lights 3 is their favourite series yet and. "This is probably, in my opinion, our most ambitious series yet in terms of what we're talking about and what we're showing and doing. "We've moved the focus a bit, as we did in series two, so the criminal arc and storyline of this series is about middle-class crime. Blue Lights has always been and always will be a confluence of the journalism that we used to do and turning it into drama - it's just how Adam and I like to work."
