One of science fiction's foundational TV texts just became a lot easier to watch. The Twilight Zone, the CBS anthology series widely regarded as one of the greatest sci-fi shows ever made, is now free to stream on Tubi, per Polygon — all 156 episodes of it.

Rod Serling's anthology has cast a shadow over the genre since its original run, with its twist-driven morality plays echoing through everything from Black Mirror to decades of horror and sci-fi filmmaking. Having the full original series parked on a free, ad-supported platform removes the subscription gatekeeping that has shuffled classic shows between paid services for years.

The timing lands neatly on Halloween weekend, when the show's eerier entries make for natural seasonal viewing. For younger viewers who know the series mostly through parodies and references, it's a low-friction chance to see where half of modern genre television's tricks actually come from. Polygon's advice amounts to: catch it while the window is open — streaming availability has a way of entering, and exiting, another dimension.
