GAME of Thrones may hog the limelight as the premier TV hit filmed in Northern Ireland - but Line of Duty is quickly laying claim to that crown.
It was initially overshadowed as the 'other' BBC crime drama filmed in Belfast due to the success of The Fall.
But while the Jamie Dornan-starring thriller limped to a close last year amid mixed reviews, Line of Duty has grown in popularity among both audiences and critics alike.
And rightfully so, largely for being the opposite of The Fall.
The Belfast-set drama was maligned for its glacial pace, dragging a third series out of a story that should have been wrapped up in two.
Line of Duty on the other hand – centred on the work of police anti-corruption unit AC12 – is a sharply edited thrill-ride full of shocks and twists. No episode here is filler.
While it might suspend reality with many of its action scenes and cliffhangers, the procedural elements give the show a grounding.
Surprisingly, the interview room is where the show delivers its most exciting scenes and the drama excels.
Armed only with document-filled binders and touchscreens detailing evidence, our AC12 heroes clinically dissect the arguments of coppers in a bid to uncover police wrongdoing.
The show also manages to include some social comment, such as the head of police in the latest series bemoaning the lack of progress on solving a major crime.
"They've been killing us on Twitter," he says dispiritedly.
It's a testament to the show's winning formula that it has bagged many acclaimed actors for lead roles - including Enniskillen-born Adrian Dunbar - over the course of its four series.
But even after attracting such star power, the show isn't afraid to bump them off unexpectedly – helping to keep the twists turning.
If you've missed all this action, there's plenty of time to catch up. The next season isn't expected to air until 2019.
