Sci-fi Surprises in the Roku Channel Vault
It’s easy to think of Roku as just a streaming platform for devices, but the Roku Channel itself actually runs a surprisingly successful free streaming service crammed with a wide range of shows. For sci-fi fans, it’s a real treasure trove.
Haven: A genuine hit on SYFY in the 2010s, Haven is loosely based on Stephen King’s story The Colorado Kid. The show offers small-town mystery vibes with a supernatural twist, exploring psychic powers and unresolved questions over five seasons. The cast—Emily Rose, Lucas Bryant, and Eric Balfour—had undeniable chemistry.
The Outer Limits (1995 revival): Much like a darker, more mature version of The Twilight Zone, this series revived the 1960s anthology for seven seasons and over 150 episodes through the late 1990s and early 2000s, originally airing on Showtime and later SciFi Channel. Known for its impressive guest roster, you could spot Mark Hamill, Amanda Tapping, Ryan Reynolds, Kirsten Dunst, and Robert Patrick over the years.
Continuum: This lesser-known Canadian time travel show ran as a SYFY original and followed a cop from the future who goes back in time to prevent criminals from changing history. Rachel Nichols stars, and the show explores the chaos and consequences of time travel.
The Triangle: Back when SciFi Channel still took big creative swings with ambitious miniseries, The Triangle focused on the Bermuda Triangle. Written by Rockne S. O’Bannon and Dean Devlin, and starring Sam Neill, Eric Stoltz, Catherine Bell, and Lou Diamond Phillips, it offered high-concept sci-fi adventure.
Relic Hunter: If you ever wondered what a budget 1990s-style live-action Tomb Raider knockoff starring Tia Carrere might look like, this short-lived syndicated show is it. Carrere plays a professor globe-trotting in search of mysterious treasures. The formula is familiar, but the adventure is fun.
Lexx: Even sci-fi diehards sometimes forget Lexx. It ran for four seasons on SciFi Channel around the turn of the millennium, during a period when the network was experimenting with its direction. The show is dark, comedic, sexy, and unapologetically bizarre.
Sanctuary: This SYFY original debuted in 2007 as an experimental web series before getting picked up for TV. Amanda Tapping, post-Stargate SG-1, stars as a scientist who studies unusual and wild creatures. The series was one of the first shot almost entirely using green screen, giving it a distinct, if now somewhat dated, visual style.
Tin Man: Not to be confused with Wicked, this quirky revisiting of the Wizard of Oz concept premiered as a SYFY miniseries in 2007. The cast included Zooey Deschanel, Alan Cumming, Neal McDonough, Kathleen Robertson, and Richard Dreyfuss. It drew large ratings and reportedly cost $20 million to produce.
Farscape: Perhaps not “forgotten” but definitely underwatched lately, Farscape remains a standout sci-fi series. It was the benchmark that put SciFi Channel on the map for original content, featuring a bold mix of puppetry and practical effects that still feel unique, alongside imaginative stories that rival Star Trek and Star Wars.
The Dresden Files: Adapted from Jim Butcher’s urban fantasy book series, this 2007 SYFY show was well-received by critics and genre fans but didn’t draw enough viewers to last beyond a single season. Paul Blackthorne starred as wizard/private eye Harry Dresden. The series ran for just twelve episodes. As one viewer put it:
“If the Dresden Files series had been called anything else… It was a good series if you'd never read the Dresden Files. It even got me to read the books … after which I found out why so many people didn't like it. It was horrible as an adaptation. Not actors' fault, they did the best you could expect.”
Even with its flaws, it's still an interesting watch, especially if you’re curious about Chicago’s magical underbelly.
