The Thin Blue Line Documentary Review – A True Crime Classic That Changed Everything

TUBI | 1 Episode | 1988

Rating: 4 out of 5 – A masterclass in justice and style... minus the lower thirds.

Opening the File

Today, instead of chasing the latest documentary drop like a content gremlin, I cracked open the vault. A quick search for “best true crime documentary ever made” led me past a few familiar faces and straight into a name I had crossed paths with in the past but ignored. The Thin Blue Line. Over 35 years old and still commanding reverence like a cult classic with a badge, it popped up on list after list like a ghost that refuses to rest. I’d never watched it before. That felt criminal enough. So, I cued it up (lucky me, it’s streaming free on TUBI) and settled in to see what all the righteous noise was about.

The Case According to Texas

It starts like a throwaway encounter: Randall Adams, a traveler with a dead engine, gets picked up by 16-year-old runaway David Harris. They drink, they smoke, they watch a movie. After that, the story splits in two. Adams says he went back to his motel and called it a night. Harris? He claims Adams pulled the trigger during a police stop, killing Dallas police officer Robert W. Wood.

Under pressure to find a cop killer and with no other leads, detectives locked onto Adams like he was gift-wrapped. Never mind that the evidence was thinner than tracing paper. Never mind that Harris had a rap sheet stretching into the future and a crime spree already in motion. No. Adams was an adult, and Texas wanted a body for the electric chair.

Errol Morris Enters the Scene

Director Errol Morris peels back the skin of a Texas murder case and finds a mess of bias, bad faith, and the kind of “justice” that looks more like performance art. The murder of a Dallas police officer in 1976 is revisited through dramatic re-enactments and chilling contradictions, peeling back the glossy surface of justice to reveal something far more sinister. The flimsy circumstantial evidence. The inconsistencies ignored. The gaping hole where motive and method should meet. The deeper he digs, the clearer it becomes. This wasn’t just a rush to judgment. It was orchestrated by the Texas police department.

Cinema with a Badge and a Pulse

This isn’t your average true crime doc—it’s more like if film noir and investigative journalism had a slow-burning love affair. The Thin Blue Line blurs the boundary between documentary and art house cinema, complete with stylized, highly engaging re-enactments, interviews sharp enough to draw blood, and a Philip Glass score that pulses beneath the story like a second heartbeat. There’s no narrator here, just the voices of those tangled in the case, leading you through a maze of memory and motive.

Missing Names, Missing Pieces

Now, if you've read any of my reviews before, you already know I have a personal vendetta against docs that flash a name on screen for 0.2 seconds like it’s a subliminal message. Ideally, that label stays up the whole time the person’s on screen. But Morris? He said no name tags for anyone. None. Zip. I actually laughed out loud. Like, full goblin cackle.

Naturally, I went down a rabbit hole to learn what these name labels are officially called. Turns out, they’re “lower thirds”—a.k.a. Name Supers, a.k.a. Chyrons. Thanks, Wikipedia. They’ve been around since the '60s, so Morris can’t plead ignorance. Still, I’ll cut him a little slack. The film is almost 40 years old, and honestly, the lack of labels weirdly adds to the dreamlike ambiguity. That said, it does turn the whole experience into a bit of a guessing game. If the guy’s in a suit? Probably a cop. If he’s sitting in front of a backyard fence? Probably one of David Harris’s old hangouts.

Despite the chaos, the timeline stays fairly linear, and most of these people speak with enough weight that you catch on.....eventually. But let’s not lie: a few name tags wouldn’t have killed the mood. Might’ve even saved us a bit of whiplash.

A Masterclass in Mistrust

This one’s a knockout—equal parts gripping, sobering, and strangely elegant. The Thin Blue Line doesn’t just document injustice; it dismantles it, brick by brick, with the precision of a scalpel and the eye of an artist. It’s a rare breed: thrilling without exploitation, compassionate without sentimentality, and bold enough to question the system without ever slipping into melodrama. Morris doesn’t just tell a story—he interrogates it. The result? A genre-defying crime documentary that rewrote the rulebook while exposing the cracks in the courthouse floor.

It’s a masterclass in restraint and revelation. The film holds up a mirror to the justice system, not just to show us how wrong it can get, but how often we ignore the evidence staring us in the face. Decades later, this story of a wrongful conviction still echoes, because the problem hasn’t gone away. The names change, but the machinery grinds on.

Final Verdict

Injustice never looked so elegant, or so damning. Journalistic filmmaking at its finest. Powerful. Haunting. Four stars, easily. If not for the missing lower thirds, we might be talking perfection. There’s a reason this film keeps popping up on “best of” lists even decades later, and hopefully, this The Thin Blue Line documentary review has shown why it still matters.
