You know that feeling when the credits roll on a heavy episode of Chicago P.D. and you're just sitting there in the dark? It’s that specific mix of adrenaline and moral exhaustion. Hank Voight is basically the king of the "gray area," and once you get used to that kind of storytelling, regular police procedurals feel kinda... fluffy. You want the grit. You want the characters who make terrible decisions for what they think are the right reasons.
Finding shows like Chicago PD isn't just about finding another cop show. It’s about finding that specific brand of "Intelligence Unit" intensity where the badge is more of a suggestion than a rule book. Honestly, most shows try to do this and fail because they're too scared to make their protagonists genuinely unlikable for a minute.
Dick Wolf’s One Chicago universe has a very specific DNA. It’s fast. It’s dirty. It’s deeply rooted in the city of Chicago itself. To find something that scratches that same itch, you have to look for shows that prioritize the internal politics of the precinct and the psychological toll of the job over the "case of the week" format.
Why The Shield Is Still the Gold Standard
If you haven't seen The Shield, stop what you’re doing. Seriously. If Voight’s tactics make you lean in, Vic Mackey will make you fall off your chair. This show premiered on FX back in 2002, and it basically rewrote the rules for what a TV cop could be. It follows the Strike Team in a fictionalized district of Los Angeles.
Vic Mackey isn't just "rough around the edges." He’s a criminal. But he’s a criminal who catches other criminals. The show forces you into this uncomfortable position where you’re rooting for a guy who is actively breaking the law. It’s much darker than Chicago P.D., mainly because the consequences in The Shield feel permanent. There’s no reset button at the end of the season.
The pacing is relentless. You get that handheld, documentary-style camera work that makes everything feel frantic. It captures that same "us against the world" mentality that the Intelligence Unit has. If you love the scenes where Voight takes someone to the "silo," The Shield is basically seven seasons of that energy. It’s uncomfortable, brilliant, and arguably the best police drama ever made.
The Gritty Realism of Southland
Southland is the show people usually overlook, which is a shame. It was too real for NBC, so it moved to TNT before eventually being canceled. It doesn't have the glossy finish of a Dick Wolf production. It feels raw.
What makes it one of the best shows like Chicago PD is the focus on the patrol officers and detectives as actual human beings. You see the burnout. You see how a single 12-hour shift can erode someone’s soul. Ben Sherman’s journey from a rookie to a hardened vet mirrors some of the arcs we’ve seen with characters like Kevin Atwater or Kim Burgess, but it’s told with a bit more cynicism.

Regina King is phenomenal in this. Her performance as Detective Lydia Adams is a masterclass in subtlety. She deals with the horrific things she sees on the job by withdrawing, and the show captures that isolation perfectly. It’s not about huge explosions or high-speed chases every five minutes; it’s about the quiet, heavy moments that happen between the calls.
Bosch: The Modern Noir
If you want something that feels a bit more "prestige" but still keeps the grit, Bosch on Amazon Prime is your best bet. Based on Michael Connelly’s novels, it follows Harry Bosch, a homicide detective who is perpetually at odds with the department’s hierarchy.
Harry isn't a rule-breaker in the same way Voight is—he’s actually a bit of a stickler for the "mission"—but he has that same relentless, obsessive quality. He can’t let go of a case. The show captures the atmosphere of Los Angeles in the same way Chicago P.D. captures the Windy City. The city is a character.
It’s a slower burn. You have to be okay with a story taking ten episodes to resolve one or two major cases. But the payoff is always there. It’s smart, adult television that doesn't feel the need to over-explain everything to the audience. Plus, the jazz soundtrack and Harry’s hilltop house give it a vibe that is completely unique in the genre.
The International Perspective: Line of Duty
Sometimes you have to look across the pond. Line of Duty is a British series that focuses on AC-12, a unit that investigates—wait for it—other cops. It’s the Internal Affairs version of Chicago P.D..
You might think a show about "anti-corruption" would be boring and bureaucratic. You would be wrong. The interrogation scenes in Line of Duty are more tense than most action movies. They are long, 15-minute sequences of dialogue where characters are tripped up by their own lies.
It explores the idea of the "bent copper" with incredible depth. Just like how Voight often crosses the line to get a result, Line of Duty asks what happens when that line becomes invisible. It’s twisty, fast-paced, and incredibly addictive. Once the "Caddy" storyline starts, you won't be able to stop watching.

Blue Bloods vs. Chicago P.D.: A Different Kind of Family
A lot of people recommend Blue Bloods as a companion to Chicago P.D., but they’re actually very different beasts. Blue Bloods is much more "Law and Order" than "Gritty Cable Drama." It’s about the Reagan family and their multi-generational commitment to the NYPD.
It’s a "comfort" show. You know there’s going to be a Sunday dinner. You know Frank Reagan (Tom Selleck) is going to deliver a moral monologue that settles everything. It lacks the "dirty" feel of the Intelligence Unit, but it hits that same craving for procedural competency. If you like the ensemble aspect of the One Chicago world, you’ll appreciate the Reagans. Just don't expect Voight-level brutality.
The Raw Power of The Wire
We can’t talk about shows like Chicago PD without mentioning The Wire. However, a word of caution: The Wire is not a procedural. It’s a visual novel. It’s a systemic look at the city of Baltimore through the eyes of the police, the drug dealers, the politicians, and the schools.
It’s dense. It’s realistic to the point of being painful. If you like the episodes of Chicago P.D. that deal with the politics of the Mayor’s office or the systemic issues in the neighborhoods, The Wire takes those themes and turns them up to eleven. It shows you exactly why the "war on drugs" is a stalemate. It’s essential viewing for anyone who wants to understand the complexity of modern policing.
Special Mention: FBI and FBI: Most Wanted
Since these are also Dick Wolf shows, they share a lot of the same DNA. FBI is more of a straight-down-the-middle procedural, focusing on the New York field office. It’s efficient and polished.
FBI: Most Wanted, on the other hand, feels a bit more like Chicago P.D. because it follows a specialized mobile unit. They’re always on the move, chasing the worst of the worst. There’s a certain ruggedness to the team, led originally by Julian McMahon’s Jess LaCroix. It has that "hunt" energy that makes the Intelligence Unit so fun to watch.
Why We Keep Coming Back to the Gritty Procedural
There’s something about the "flawed hero" that works so well in a police setting. We like to imagine that there are people out there willing to do the dirty work so we don't have to. Chicago P.D. taps into that fantasy perfectly. Voight is the guy we fear but also secretly want on our side when things go sideways.

The shows mentioned above all play with that same tension. They ask us where we draw the line. Is it okay to beat a suspect if it saves a kidnapped child? Is it okay to lie on a report to keep a "good" cop on the street? These shows don't give easy answers, and that’s why they stick with us.
Actionable Ways to Find Your Next Favorite
If you're still undecided on where to start, here’s a quick roadmap based on what you specifically like about the Intelligence Unit:
- For the Voight fans: Watch The Shield. It is the only show that matches—and exceeds—the moral complexity of Hank Voight.
- For the Atwater/Burgess fans: Try Southland. It captures the emotional weight of being a beat cop in a way no other show does.
- For the Halstead/Upton fans: Go for Line of Duty. The romantic and professional tensions within the unit are top-tier.
- For the Chicago setting fans: Try Bosch. While it’s LA, the city is just as integral to the plot as Chicago is to P.D..
- For the pure adrenaline junkies: S.W.A.T. (the Shemar Moore version) is a lot of fun. It’s less "gritty" and more "action-movie," but it’s great for a high-energy binge.
Most of these are available on major streaming platforms like Hulu, Max, or Amazon Prime. The Shield is often on Hulu, while Southland can be a bit harder to track down—sometimes it’s on Tubi or available for digital purchase. Line of Duty is a staple on BritBox and often parts of it are on Hulu or Prime as well.
Start with one pilot episode. Most of these shows find their footing very quickly. You’ll know within twenty minutes if the vibe is right. Just don't expect a happy ending every time—that’s not how these stories work. They’re about the grind. They’re about the city. They’re about the badge and everything that gets stuck to it.
Once you finish these, you might find yourself looking at the "One Chicago" world a little differently. You’ll start seeing the tropes and the patterns. But that’s the fun of being a fan of the genre. You learn the language of the street, the precinct, and the interrogation room. You start to see the shades of gray everywhere.
The best next step is to head over to a streaming service and search for The Shield. It is the most direct ancestor to the type of storytelling Dick Wolf perfected with the Intelligence Unit. If you can handle the standard definition of the early seasons, the writing will absolutely floor you. It's a journey that stays with you long after the final episode ends.
Actionable Insight:
If you're hitting "choice paralysis," start with The Shield if you want intensity, or Bosch if you want a smart, moody detective story. Both are long-running series with satisfying conclusions, meaning you won't be left with a cliffhanger that never gets resolved. Avoid jumping into The Wire unless you are ready to give it your full, undivided attention; it's not a "background" show.
