This is a listicle feature identifying seven classic science fiction television series from the 20th century that, in the author's view, remain superior to most sci-fi shows being produced today. While acknowledging that modern sci-fi TV, such as Black Mirror and Severance, is strong, the piece argues that these older shows laid the groundwork for the genre and can still hold their own against the best contemporary offerings.

The list includes The Outer Limits (1963–1965), an ABC anthology series that emerged in the wake of The Twilight Zone's success but carved out its own identity by sticking to pure science fiction and horror rather than supernatural fantasy, praised for its inventive premises despite a limited budget. Also featured is Stargate SG-1 (1997–2007), described as one of the finest military sci-fi shows ever made, noted for its world-building and balance of episodic and serialised storytelling, and considered superior to the 1994 film that spawned the franchise. The article also references Babylon 5 as another entry on the list, though the full ranking and remaining entries are not detailed here.
