Unbelievable: The Netflix True-Crime Drama With A 98% Rotten Tomatoes Score

Some true-crime dramas are driven by shocking revelations. Unbelievable takes a different approach, placing the people affected by the crimes at the centre of its story and showing how devastating it can be when a victim is not believed.

The eight-part Netflix limited series, released on September 13, 2019, follows a teenager whose report of rape is questioned by police, while two female detectives in Colorado begin investigating a series of remarkably similar assaults. The story is inspired by true events.

That combination of gripping investigation, strong performances and an unusually empathetic perspective has helped Unbelievable maintain its reputation years after its release. Rotten Tomatoes currently lists the series at 98% from 84 critic reviews, with an 89% audience score.

A Story That Puts The Victim At The Centre

At the heart of the series is Marie Adler, played by Kaitlyn Dever.

After Marie reports that she was sexually assaulted by an intruder, the investigation takes a devastating turn when the detectives handling her case begin questioning her account. Under growing pressure, Marie eventually recants her story, leaving her to deal with the consequences of not being believed.

Netflix’s synopsis establishes Marie’s experience alongside a second investigation taking place hundreds of miles away. There, detectives Grace Rasmussen, played by Toni Collette, and Karen Duvall, played by Merritt Wever, encounter similar cases involving attacks by an intruder.

As the two detectives compare what they are seeing, the possibility that the cases are connected becomes increasingly difficult to ignore.

Two Investigations, One Troubling Connection

The series deliberately moves between Marie’s experience and the Colorado investigation.

Marie is left dealing with the emotional and practical fallout of her decision to retract her report, while Karen and Grace gradually begin piecing together evidence from other cases.

Their investigation takes them beyond individual incidents as they search for a larger pattern and eventually work with the FBI. Netflix’s episode guide shows how the story develops across the eight episodes, from Marie’s initial report and its aftermath to the detectives’ attempts to identify the perpetrator and prepare for court.

That parallel structure gives Unbelievable two very different perspectives on the same underlying problem: what happens when one investigation fails to recognise the truth, and what can happen when investigators keep looking for it.

Inspired By A Real Investigation

The story has a substantial real-world foundation.

Unbelievable was inspired by “An Unbelievable Story of Rape,” the 2015 article by T. Christian Miller and Ken Armstrong published through The Marshall Project and ProPublica. The reporting later became the basis for the 2018 book A False Report: A True Story of Rape in America. The story also inspired the This American Life episode “Anatomy of Doubt.”

The television series was created by Susannah Grant, Ayelet Waldman and Michael Chabon, with Grant serving as showrunner. Netflix describes the project as a story of trauma, determination and resilience inspired by the documented events.

That connection to real reporting gives the drama an added weight. Although it is a scripted adaptation, its central investigation is rooted in real cases and journalism.

Kaitlyn Dever, Toni Collette And Merritt Wever Lead The Cast

The three central performances are provided by Kaitlyn Dever, Toni Collette and Merritt Wever.

Dever plays Marie, whose experience drives much of the emotional story. Collette plays Grace Rasmussen, while Wever portrays Karen Duvall, the two detectives whose investigation gradually reveals the wider pattern.

The ensemble also includes Eric Lange, Bill Fagerbakke, Elizabeth Marvel, Bridget Everett, Danielle Macdonald, Dale Dickey, Liza Lapira and Omar Maskati.

The central performances received significant awards recognition. All three leads were nominated at the Golden Globes, while Collette also received a Primetime Emmy nomination. The series itself earned four Primetime Emmy nominations, including Outstanding Limited Series, Outstanding Writing for a Limited Series, Outstanding Casting and Outstanding Supporting Actress for Collette.

Why Critics Responded So Strongly

The critical response to Unbelievable has focused heavily on its decision to move beyond the conventions of a standard police procedural.

Rotten Tomatoes’ current critics’ consensus describes the series as a powerful true-crime drama that shifts its attention towards survivors rather than treating the crimes simply as mysteries to be solved.

That distinction is reflected in the show’s deliberate pace. Instead of relying on constant twists or sensationalism, the eight episodes spend time showing the consequences of the assault, the investigation and the institutional failures surrounding Marie’s case.

The Peabody Awards recognised this approach when Unbelievable won a 2019 Peabody Award. The organisation highlighted the contrast between the Washington and Colorado investigations and praised the series for its humanised portrayal of rape survivors.

Eight Episodes That Build Toward The Truth

The limited series unfolds across eight episodes, with the two storylines gradually moving closer together.

The opening episodes establish Marie’s account and the fallout after she retracts it. Three years later, Karen begins investigating a strikingly similar assault in Colorado, prompting her to work with Grace as they compare their cases.

As the investigation progresses, the detectives identify additional victims and seek help connecting the cases. New leads eventually take Karen across state lines, while Grace takes increasingly direct steps in the investigation.

By the final episodes, the detectives are racing to identify the perpetrator and make an arrest, while Marie’s own circumstances continue to deteriorate. The eighth episode brings the separate threads together as Karen and Grace prepare for a pivotal day in court.

The result is a tightly focused story that maintains the tension of a police investigation without losing sight of the human cost behind it.

A True-Crime Drama With A Different Focus

What continues to distinguish Unbelievable is the way it treats the crime itself as only part of the story.

The investigation matters, but so do the people living through its consequences. Marie’s experience and the detectives’ search for answers are presented side by side, allowing the series to explore both the damage caused when an account is dismissed and the painstaking work required to uncover the wider truth.

That approach has helped the series maintain a strong critical reputation. Rotten Tomatoes currently gives it a 98% Tomatometer score from 84 reviews and an 89% audience score, while the Peabody Awards recognised its combination of investigative storytelling and humanised treatment of survivors.

For viewers looking for a true-crime drama that is tense without being sensationalised, Unbelievable remains a compelling eight-episode watch.

Unbelievable is available to stream on Netflix.
