Line of Duty Returns: How the Crime Thriller Plans to Fix Its Finale and Follow Dexter’s Revival Formula

Line of Duty’s Comeback: A Fresh Start After a Divisive Finale

Line of Duty is gearing up for a major comeback with its seventh season, aiming to regain the trust and excitement of its fanbase after its last season left audiences divided. Widely recognized as one of Britain’s most influential crime dramas, the series has pushed the boundaries of TV procedurals with intricate plotting and relentless suspense, especially surrounding the anti-corruption unit AC-12. But the controversial season 6 finale, with its much-hyped ‘H’ reveal, fell flat for many, making the return of Line of Duty a high-stakes moment for both creators and fans.

Why the Final Reveal Broken the Spell

The power of Line of Duty was always its web of corruption, tension-filled interrogations, and conspiratorial mysteries. Fans invested years in guessing the identity of ‘H’ – only to be left cold when the answer was finally delivered with a deliberate anti-climax. The exposure of Ian Buckells as the criminal mastermind felt less like a grand culmination and more like a compromise, blunting the show’s trademark sense of consequence and institutional reckoning. AC-12’s uphill battle against corruption suddenly seemed toothless, missing the cathartic justice or emotional devastation the audience had been waiting for.

Lessons from Dexter: The Double-Edged Sword of TV Revivals

Line of Duty isn’t the first prestige crime drama to find itself in this position. Dexter, an American juggernaut in the genre, faced a similar crisis. After a finale that sent its antihero off to a life of anonymity as a lumberjack, viewers felt robbed of the psychological closure the series had meticulously constructed. Like Line of Duty, Dexter’s first revival, Dexter: New Blood, attempted to recapture what once worked – nostalgia, tension, and moral ambiguity – but ultimately delivered another ending that proved divisive, as developments felt more engineered than earned.

It wasn’t until the next chapter, Dexter: Resurrection, that the series found its rhythm again. By prioritizing long-form character arcs, tighter plotting, and moral consequences, the show delivered a sharper storyline that respected its origins while enticing both longtime fans and new viewers. This shift was pivotal, and it’s a playbook Line of Duty’s creators are now studying closely.

What Line of Duty Can Learn from Dexter’s Reinventions

Reviving a crime drama isn’t about simply bringing characters back – it’s about restoring the suspense, stakes, and authenticity that made the original series special. Dexter: Resurrection succeeded by slowing down, embracing difficult truths, and allowing character and story to evolve with real stakes. Line of Duty’s season 7 could benefit from:

• Paced Storytelling: Letting conspiracy plots, investigations, and interrogations breathe instead of rushing to bombshell twists.
• Earned Revelations: Ensuring that each clue and plot turn is built on psychological logic and narrative groundwork, not just shock value.
• Tonal Consistency: Maintaining the show’s signature blend of realism and nerve-wracking suspense without softening its edge.
• Character-Driven Drama: Centering moral dilemmas and institutional complexities over procedural gimmicks.

What’s Next for British Crime TV

The stakes for Line of Duty’s return go far beyond simply wrapping up loose plot threads. Viewers want the series to feel both familiar and re-energized – a tough balance that American and British crime dramas alike have struggled with in this era of revivals and soft reboots. Applying the lessons learned by Dexter’s creative team – especially avoiding shallow nostalgia and focusing on earned, satisfying storytelling – could make Line of Duty’s next season a new blueprint for how to rebuild a beloved TV legacy.
