Netflix has repeatedly turned to books, comics and anime for ambitious screen adaptations, but a recognizable title and devoted fan base do not guarantee a satisfying result. Some projects have drifted too far from their origins, while others have stayed so close that they struggled to justify their existence.

From a divisive animated reinvention to live-action anime experiments and dark reworkings of familiar characters, these 10 Netflix adaptations fell short of expectations in distinctly different ways.

Comic-book heroes and radical reinventions

Iron Fist arrived as part of Netflix’s live-action Marvel lineup alongside “Daredevil,” “Jessica Jones” and “Luke Cage,” with the characters ultimately feeding into a team-up series. The result, however, was a low-energy adaptation that failed to capture the comics’ appeal. Finn Jones’ performance was criticized as timid, and Iron Fist eventually became a target of jokes even among the Defenders. Despite that reception, the character is getting another opportunity through the upcoming third season of “Daredevil: Born Again” on Disney+.

Scott Pilgrim Takes Off took the opposite problem and made it the point. The animated show reunited the cast of Edgar Wright’s “Scott Pilgrim vs. the World” as voice actors, but creators Bryan Lee O’Malley and BenDavid Grabinski did not simply retell the graphic novels. They built an alternate version of the story that played with reboots, legacy sequels and live-action adaptation itself, even incorporating the production of Wright’s movie into the show. Many fans considered the result terrific; others who wanted a straightforward recreation were disappointed.

Dead Boy Detectives, based on Neil Gaiman’s characters, was not an especially difficult watch. Its frustration came from its limited connection to the larger world around it. Although set in the same universe as Netflix’s “The Sandman,” its links largely amounted to brief appearances by Kirby Howell-Baptiste’s Death and Donna Preston’s Despair of the Endless. The project also had a complicated path to Netflix: It began as an HBO Max “Doom Patrol” spin-off after the characters appeared in a backdoor pilot during that show’s third season.

Anime adaptations with different problems

Cowboy Bebop, released in 2021, followed outer-space bounty hunters through a Western-noir-inspired setting. The live-action series delivered energetic action and a capable cast, with John Cho handling Spike Spiegel’s humor and the choreography’s violence and gore. Yet its commitment to recreating the anime left the production feeling like a less compelling imitation. For viewers who already loved the original, the series offered too little reason to choose the remake.

The Fullmetal Alchemist trilogy began in 2017 as a live-action production from Netflix and Warner Bros. The three films—two released in quick succession—follow the Elric brothers after their attempt to resurrect their mother through alchemy leaves one without limbs and the other without his body. Translating that magical world through CGI and live-action performances often made the material feel more like self-parody than a convincing adaptation. The trilogy did have bright spots and used an all-Japanese cast, avoiding the whitewashing criticism directed at some comparable anime adaptations.

Strong premises undermined by pacing

Pieces of Her, adapted from Karin Slaughter’s novel, opens with a striking mystery. A mother, played by Toni Collette, displays unexpected heroism when she and her adult daughter are caught in a public mass shooting. The series then relies heavily on long flashbacks to explain her past, slowing the central story rather than steadily revealing it. The episodes also expand in length, from a 44-minute premiere to a finale running more than an hour. Critics largely regarded Collette’s performance as the series’ strongest element.

Behind Her Eyes became a six-part miniseries in 2021, drawing from Sarah Pinborough’s 2017 novel. Its story centers on a single mother having an affair with a married man, before the secrets of his wife—including her ability to astral project—push the narrative into stranger territory. Several slow episodes of exposition give way to a concentrated rush of twists, producing a finale filled with surprises but lacking sufficient substance to reward the six-hour investment.

When a familiar character changes beyond recognition

Ratched attempted to create an origin story for Nurse Mildred Ratched from “One Flew Over the Cuckoo’s Nest.” Sarah Paulson took over the role played in the film by Louise Fletcher, with frequent collaborator Ryan Murphy producing. The premise offered room to work backward from a villain and find a more sympathetic figure. Instead, a TVLine review argued that the series resembled an unused “American Horror Story” concept, favoring elaborate shocks and melodrama over a deeper character study.

The Chilling Adventures of Sabrina followed the success of “Riverdale” by transforming another Archie-related property into darker television. The young witch must choose between fully embracing witchcraft and maintaining ties to the mortal world, but the Netflix series surrounded that choice with warlocks, witches, mystical creatures, sex and other adult material. That tone sharply contrasted with the lighthearted comics and the family-friendly image reinforced by Melissa Joan Hart’s “Sabrina the Teenage Witch” sitcom. The production was accomplished, but its lack of comedy limited its appeal to casual viewers.

Daybreak retained very little of Brian Ralph’s comic book beyond its basic foundation. The comic is a restrained story about relationships forming during a hopeless zombie apocalypse; the Netflix version became a flashy, high-school-driven adventure set in a post-apocalyptic Glendale, California. Jocks became sadistic tribes, cheerleaders became Amazonian warriors, and zombie-human hybrids roamed the wasteland. Some of its coming-of-age ideas worked, but fans immediately noticed how little remained of Ralph’s approach. Netflix canceled the show after one season.

ShowBiz Take

The most revealing part of this list is that adaptation failure has no single formula. “Cowboy Bebop” was faulted for adhering too closely to its anime without recreating its impact, while “Daybreak” disappointed by barely resembling its comic. “Scott Pilgrim Takes Off” deliberately rejected a simple retelling and divided viewers even though many fans admired the experiment.

That contrast is why recognizable source material is only the starting point. These projects show that fidelity can involve tone, pacing, character and purpose—not merely repeating plot points. An adaptation must preserve what made the original compelling while also finding a reason to exist in a different medium.

What Happens Next?

“Daybreak” will not continue beyond its first season, but Iron Fist has another chance to change the conversation. The character is due to return through “Daredevil: Born Again” Season 3 on Disney+, providing a new opportunity after the disappointing reception to his Netflix series.
