Screen Rantand Slashfilm slashfilm.comhave consistently ranked “Future Man,” “Loki,” and “Russian Doll” among the 10 greatest time travel shows of the 21st century—crediting their inventive plots, sharp character work, and surprising genre versatility. These series stand out not just within the time travel subgenre, but are often cited in discussions about the greatest time travel showsmodern TV has to offer. Shows like “The Lazarus Project” (2022–2024) and “Undone” (2019–2022) reflect the decade’s growing appetite for nonlinear storytelling and temporal paradox, solidifying their status among the 10 Greatest Time Travel Shows Of The 21st Century (So Far). Audiences haven’t just watched— they’ve truly loved these genre experiments.
That acclaim, tying commercial success to adventurous narratives, helped push time travel further into the pop culture spotlight. Across the TV industry, “Future Man” and “Undone” also sparked creative risks—proving that viewers were ready for bold storytelling with high-concept time loops and innovative uses of time travel.
Rotoscope animation in “Undone,” for example, allowed writers and animators to redefine how TV explores perceptions of time, breaking visual and narrative rules most genre series still follow. That approach made “Undone” feel genuinely distinct and put it squarely among the greatest time travel shows of the 21st century . “The Melancholy of Haruhi Suzumiya” (2006–2009), as the lone anime entry, demonstrated the genre’s breadth by weaving cosmic timelines into high school drama. The 2010s and 2020s marked a period of rapid evolution for 21st century time travel TV. New releases fiercely competing for fan and critic attention across Netflix, Amazon Prime, and cable networks, as noted by Tvline.
Genre reinvention and audience reaction
Critics at Slashfilm ( slashfilm.com ) and Tvline say 21st-century time travel shows succeed best when they combine classic sci-fi mechanics with bold, contemporary themes. According to Slashfilm’s longform analysis , “Loki” (debuting in 2021) leverages Marvel’s sprawling universe to pick apart fate and free will. Giving viewers a fresh take on existential stakes and earning its place among the 10 Greatest Time Travel Shows Of The 21st Century (So Far) . “Outlander” (2014–) pulls millions into historical drama rooted in the heartbreak of temporal dislocation, cementing its role as one of the greatest time travel shows currently running. That mass appeal isn’t luck. Major rankings highlight “Russian Doll” (2019–2022) as a true crossover hit: its “Groundhog Day” concept meets sharp existential dilemmas. Natasha Lyonne’s lead performance drew nearly universal acclaim and that rare flawless Rotten Tomatoes score.
Tvline points out these shows resonate because they make time travel personal—anchoring far-out speculation to relatable stakes and emotional narratives. It’s not just about tangled timelines; it’s about identity, trauma, and individual choice. That format variety is striking: animation in “Undone,” irreverent satire in “Future Man,” or multiverse plotting in “Loki” all show just how flexibly writers now wield time travel as a storytelling device for modern TV.
What it means
The rise of ambitious time travel television reflects a larger shift in how serialized stories are made—and how they’re watched—in this fragmented, on-demand era. Screen Rant points to how successes like “Travelers” (2016–2018) and “12 Monkeys” (2015–2018) demonstrate that complex, looping timelines don’t scare off viewers anymore and, in fact, are crucial for the best and greatest time travel shows of the 21st century.
So, with producers locked in fierce competition for attention, it’s those creative risks with structure and tone that set shows apart. We’ve seen series like “DC’s Legends of Tomorrow” embrace brash, self-aware pastiche—while “The Lazarus Project” opts for tense, slow-burn suspense.
This innovation race has made time travel a core part of modern genre TV, with stakes ranging from critical acclaim to launching whole new franchises. As of June 2026, time travel is one of the most revisited themes in pilot scripts being reviewed by major trade publications, supporting the idea that the 10 Greatest Time Travel Shows Of The 21st Century (So Far)are inspiring even more creators and audiences.
