This Collider article ranks the seven best science-fiction TV series of 2026 so far, covering a mix of new shows and returning favourites across networks, cable and streaming platforms. The writer argues that 2026 has been a particularly strong year for the genre, with sophomore seasons avoiding a slump, spin-offs matching their parent shows, and ambitious new concepts featuring high-profile casts. Apple TV+'s Silo is deliberately excluded, as the list only reflects series that have concluded their current run.

The list is led off by FX's "The Beauty" at number seven, a body-horror satire created by Ryan Murphy and based on a graphic novel, starring Ashton Kutcher as a tech billionaire behind a lethal, STD-transmitted "perfection" drug, with FBI agents played by Evan Peters and Rebecca Hall investigating its fallout. The show is framed as a commentary on beauty standards and celebrity culture in the age of GLP-1 weight-loss drugs, featuring a large ensemble cast including Anthony Ramos, Bella Hadid and Billy Eichner. The remaining six entries in the countdown were not detailed in the excerpt provided.
