Collider has published a ranked list of the 15 best science-fiction television shows released since the year 2000, highlighting how advances in production technology have allowed the genre to flourish on the small screen. The list praises both widely celebrated hits and underappreciated gems, arguing that 21st-century sci-fi television has produced some of the most ambitious and well-crafted storytelling in the genre's history.

Among the shows featured are Orphan Black, praised for Tatiana Maslany's performance as multiple clones; Apple TV+'s Foundation, an adaptation of Isaac Asimov's novels; Silo, based on Hugh Howey's books and starring Rebecca Ferguson; and The Expanse, a space opera blending political intrigue with noir elements. Each entry is accompanied by a short critical assessment explaining its strengths, from writing and performances to visual scale and thematic depth.
