One evening this 2025, Chicago Fire, Chicago Med, and Chicago P.D. aired back-to-back as part of NBC’s massive One Chicago crossover. After that triple feature, fans couldn’t stop debating: is Chicago P.D. still the grittiest slice of the One Chicago universe?
For years, Chicago P.D. sat proudly in third, airing at 10 pm with stories that pushed darker and harder than Fire or Med. But with Chicago Med now drawing bigger audiences and Chicago Fire leaning into emotional soap-style moments, the question feels more urgent than ever.
Let’s break it down and see what makes Chicago P.D. darker, how it stacks up in 2025, and whether recent changes have dimmed or sharpened its edge.
Is Chicago P.D. still the grittiest One Chicago series?
The Intelligence Unit’s darker beat
Right from its 2014 premiere, Chicago P.D. set itself apart. The Intelligence Unit takes on human traffickers, serial killers, undercover narcotics rings, and gang wars. The tone leans into shadowy alleys, heated interrogations, and moral compromise.
By contrast, Chicago Fire leans on rescue, teamwork, camaraderie and Chicago Med deals with life-and-death medicine. P.D. stays gritty because it lives in moral gray zones and gritty urban settings. The shows share crossover events - like the January 2025 gas explosion arc but P.D. always brings the grit.
Grit vs Ratings in 2025
In 2025, Chicago Med overtook the other shows in ratings. It leads One Chicago in viewership. Despite that, fans on Reddit and review sites still say P.D. feels more grounded.
One fan wrote the new Chicago P.D. season “feels quieter, more serious, with less background music,” giving it a sense of foreboding. Another called it like returning to seasons one and two of P.D. but better.
The show’s third season shift into feature-film style pacing adds to the sense that it still moves darker than Fire or Med.
Cast Changes and Tone Shifts
Chicago P.D. has seen major cast changes in recent years. Key departures include actress Tracy Spiridakos and Jesse Lee Soffer. In 2025, Arienne Mandi joined the Intelligence Unit as Naomi Kerr, a former soldier with secrets.
These moves have a ripple effect on tone. New faces mean new dynamics. But Chicago P.D. still leans into tough investigations, even as Burgess and Ruzek balance professional and personal life. That tension keeps it grounded without losing edge.
The crossover test of grit
The January 2025 One Chicago crossover was declared ambitious, feeling like three hours of a mini blockbuster. Fire started it, Med carried the medical weight, and P.D. brought it home with deep investigation, hostage rescue, and criminal stakes.
Reviewers praised how P.D. guided the finale of the arc - connecting clues, breaking power lines, and tracking threats. While Med has more viewers now, when push comes to shove in a disaster, Chicago P.D. leads the way. Their grit anchored the crossover.
Personal stakes and emotional shadows
What keeps Chicago P.D. gritty is its emotional undercurrent. Unlike Fire’s heroism or Med’s hospital ethics, P.D.’s stories often hinge on personal loss.
Voight continues grappling with the trauma of his daughter and family. Burgess nearly loses a niece in crossover bombs. Atwater and Spooner explore romance under pressure. Ruzek keeps leaning into danger even before getting married.
That character weight deepens Chicago P.D.’s stories so violence feels more personal. It’s not just cases - it’s consequences.
Cinematic feel and production value
Fans have noted Chicago P.D. still looks slicker than its siblings. While Med sometimes feels like a daytime soap in tone, P.D. invests in kinetic camera work, action sequences, nighttime street sets, and tense close-ups.
One reviewer compared recent episodes to feature films, with scenes that unfold in single takes, silent tension, or chase scenes shot by drone. That raw visual style reinforces P.D.’s label as the grittiest series in the franchise.
Has Fire or Med caught up?
Chicago Fire still feels emotionally raw, especially after losing long-time characters. But it also pivots into more soap-style storylines, making it feel lighter at times.
Chicago Med may lead in ratings now, yet reviews claim Med’s characters were sidelined in the crossover and treated more like background. While Med is serious, its hospital setting gives lighter beats that contrast sharply with Chicago P.D.’s street-level stakes.
What’s new in Chicago P.D. Season 12 and 13
Season 12 mixes darkness with personal growth. New episodes explore s*x trafficking, internal department politics, and push Voight’s violence reduction strategies.
Despite the cases, the cast still jokes and goofs between takes, reminding viewers there’s a family behind the badge. Season 13 introduces Officer Naomi Kerr, who carries secrets and a military past.
That addition promises fresh tension without softening the series. The grit remains intact as new threats emerge and the team must adapt.
Why Chicago P.D. still edges out
At its core, P.D. holds onto grit through its subject matter, tone, pacing, and character stakes. Med can go heavy with ethical crises while Fire deals with heroics.
But P.D. faces crime, corruption, and violence related not just to cases but to the system itself. It lacks the big explosions of Fire or the emotional safety net of Med. Instead it delivers tense beats, moral compromise, and plotlines that stay close to Chicago’s harsh realities.
The future grit factor
Will Chicago P.D. hold the crown as One Chicago’s grittiest series? That depends on how writers balance personal arcs with criminal cases, how new cast members shift the chemistry, and how consistently they deliver suspense.
As of 2025, it retains the edge. Whether Season 14 leans back into early-season shadow or pushes new territory with characters like Naomi Kerr remains to be seen. But fans expecting gritty police drama still look to Chicago P.D.
Final Word
There’s no denying Chicago P.D. still leads in tone, case severity, and emotional weight in the One Chicago world. While Chicago Med may win in ratings and Chicago Fire hits big in hero moments, P.D. lives in the dangerous corners of the city.
Its characters bleed, they compromise, and they chase justice in places others avoid. Even as cast and settings evolve, P.D. remains sharply focused, raw, and worthy of the label "grittiest." In 2025 it still earns that title.
