13 Fantasy and Sci-Fi TV Shows Not Returning in 2026

The past year has brought a mix of emotions for fantasy and sci-fi fans, with some of our favorite shows delivering unforgettable moments while others bid farewell. Unfortunately, not all beloved series will be making a return in 2026.

One such show is “The Wheel of Time” on Prime Video, which saw a sudden cancellation just weeks after its season 3 finale. Despite critical acclaim, declining viewership led to the show’s demise. Fans were left hanging, as the series only covered a fraction of the original book series.

Similarly, “The Sandman” on Netflix wrapped up sooner than anticipated, with the decision to end the series made early on due to limited source material and production costs. Even though not technically cancelled, the show’s conclusion left fans wanting more.

“Resident Alien” on USA Network faced a similar fate, with a fourth season serving as the final chapter. Despite a dedicated fanbase, the show struggled to maintain viewership in a changing landscape.

Netflix’s “Kaos,” featuring Jeff Goldblum, ended after just eight episodes, falling victim to the streaming giant’s quick cancellation trigger for high-cost productions. The show’s cancellation left viewers with unanswered questions and untold stories.

“Arcane,” based on League of Legends, wrapped up its story as intended by its creators, marking the end of a successful run with critical acclaim and multiple Emmy wins. The show’s hefty budget made it one of the most expensive animated series ever produced.

Lastly, “Star Trek: Lower Decks” on Paramount+ concluded after five seasons, with the creator planning for the fifth season to be the final one. Despite positive reviews and award nominations, the series met its end as part of a larger reconfiguration of Star Trek content.

As we bid farewell to these shows that have enriched our viewing experiences, we look forward to new projects and storytelling adventures that await us in the ever-evolving world of streaming entertainment.
