Shows such as “Lost,” “Fringe,” and the revived “Doctor Who” helped make the 2000s a defining decade for science-fiction television. Every era produces influential genre hits — from “The X-Files” to “Lost in Space” — but the first decade of the 21st century was particularly fertile ground for ambitious sci-fi storytelling. Several of its biggest premieres went on to shape television for years, as demonstrated by the wave of “Lost” imitators that continued appearing well into the mid-2010s.
Yet alongside those ratings successes and fan favorites were plenty of sci-fi series that failed to live up to their promise. Some have become even harder to defend with age, whether because their once-futuristic technology now looks laughably dated or because their connection to controversial creators has changed the way audiences view them. These five 2000s shows have struggled to remain relevant for very different reasons.
Television can age poorly in countless ways, and science fiction is especially vulnerable. Compared with enduring hits such as “Battlestar Galactica” and “Heroes,” the weaknesses of these shows have become increasingly obvious over time.
Mutant X
When viewers rank the best and worst Marvel television shows, they typically point to the post-2010 era, including series made for Netflix and Disney+. But live-action Marvel adaptations existed long before “Daredevil,” “Agents of S.H.I.E.L.D.,” and “Secret Invasion.” Bill Bixby’s “The Incredible Hulk” remains the best-known example, while Nicholas Hammond starred in two seasons of CBS’s “The Amazing Spider-Man.” Then came “Mutant X,” a largely forgotten series loosely tied to the mythology of “X-Men” that premiered in 2001 and ran for three seasons.
Despite the title, this was not an early television spin-off of Fox’s “X-Men” films. “Mutant X” stood on its own, following geneticist Adam Kane (John Shea) and four people who developed extraordinary powers through scientific experimentation rather than natural evolution. Hunted by the government, the group spent the series on the run. After later Marvel productions such as “Legion” delivered far more polished visions of mutant characters, “Mutant X” now looks conspicuously cheap and dated.
Legal limitations also prevented the series from using recognizable characters from the comics, making its early-2000s origins impossible to miss. In the years since, Marvel television has embraced even its most obscure comic-book creations — “M.O.D.O.K.,” for instance, found room for Hexus, the Living Corporation. Against that backdrop, it is easy to understand why “Mutant X” rarely enters conversations about Marvel’s television legacy.
Birds of Prey
The WB found a superhero formula that worked with “Smallville,” its 2001 series about a young Clark Kent. The show became a major hit and helped establish the network — later transformed through its merger with UPN into The CW — as a reliable home for DC Comics adaptations. But the network’s next major DC venture fared far worse. Premiering in 2002, “Birds of Prey” followed Helena Kyle, also known as the Huntress (Ashley Scott), Barbara Gordon, or Oracle (Dina Meyer), and Dinah Lance (Rachel Skarsten) in New Gotham City, years after Batman had apparently vanished.
Rather than following the grounded tone associated with many Batman adaptations, “Birds of Prey” leaned heavily into metahumans and the more heightened science-fiction elements of the DC universe. Critics were unimpressed, and many argued that the series lacked compelling characters. It was canceled after a single season, and the stronger DC shows that followed only made it more forgettable. Cathy Yan’s vibrant 2020 film “Birds of Prey” further overshadowed the television version.
It is difficult to return to the muted, gloomy world of the series when a louder and more colorful interpretation of the same material is readily available. Even at the time, “Birds of Prey” seemed old-fashioned beside “Smallville”; the years have only made that contrast more pronounced.
Level 9
Building a drama around cutting-edge technology is always a gamble. A concept that feels futuristic on launch can seem ridiculous within a few years, which made UPN’s “Level 9” vulnerable from the beginning. Created by Michael Connelly, Josh Meyer, and John Sacret Young, the 2000 series followed a team inside a government agency tasked with stopping cyberterrorism. Long before “CSI: Cyber” or “Scorpion,” the show imagined a world where online criminals posed a threat that required a specialized government response.
The episode titles — including “Wetware” and “Ten Little Hackers” — announced the show’s determination to sound technologically current. Unfortunately, “Level 9” offered little beyond dated internet terminology. It lacked the layered characters and inventive twists that give a procedural drama staying power, and viewers quickly lost interest. The series was removed from the schedule after only 10 episodes.
For modern audiences, there is almost nothing to offset the barrage of obsolete jargon and clumsy depictions of online life. “Level 9” survives mainly as a time capsule, but it is a remarkably tedious one. The series illustrates the danger of making technological novelty the central attraction without building a durable story around it.
Freedom
Few television projects were made obsolete by September 11 as quickly as “Freedom,” UPN’s military-themed sci-fi series that aired from October through December 2000. The show’s premise imagined the United States being seized by its own military after the president was presumed dead. It struggled to find an audience and was canceled before its full season could air. After the attacks on the World Trade Center and the Pentagon, however, its vision of domestic military upheaval took on an especially uncomfortable and dated quality.
“Freedom” depicted a dystopian America in which former Navy and Army personnel joined forces to restore order. Its restrained vision of a future nightmare felt closer to “Fahrenheit 451” than “Avatar.” Within a year, the national mood had shifted dramatically, and military thrillers such as “24” increasingly focused on threats from outside the country rather than a coup from within. The series’ limited budget, visible in many scenes, only deepened its dated atmosphere.
Had “Freedom” premiered a year later, its story, tone, and presentation might have been radically different. That timing gives the short-lived series a peculiar place among television’s most rapidly outdated productions.
Dollhouse
After Fox canceled Joss Whedon’s “Firefly” following one season, the network gave the “Buffy the Vampire Slayer” creator another opportunity with “Dollhouse,” which aired from 2009 to 2010. The series centered on the Actives, people employed by a powerful corporation that repeatedly erased and replaced their identities. Clients could then hire them for specialized assignments, choosing whichever persona or skill set suited their needs. Echo (Eliza Dushku) led a cast that also included Enver Gjokaj, Dichen Lachman, Harry Lennix, and Fran Kranz.
“Dollhouse” developed a loyal following, but its treatment of sexual autonomy and female characters was troubling from the outset. Critics were already raising those concerns when the final episodes aired in 2010. In the years that followed, abuse allegations from women who worked with Whedon — including prominent collaborators from his television and film projects — altered the context surrounding the series. Scenes depicting women being controlled, exploited, and stripped of their agency now carry an even more disturbing weight.
“Dollhouse” was never a long-running hit, but its most lasting association today is the uncomfortable reminder of the controversies surrounding its creator.
