Horizon

1964–2025 62 Seasons 1173 Episodes Documentary G ⭐ 7 / 10

Horizon is currently streaming in the US on PBS, and it treats its subject with more rigour than the format usually demands. 62 seasons is a serious commitment, but one that pays off episode after episode. Its 7/10 TMDB score, built from 34 ratings, reflects a title that consistently delivers. The access secured here is hard to overstate. Put it on tonight on PBS and see for yourself.

Horizon is not trying to be everything to everyone, and that focus is exactly what makes it work. Horizon resists the urge to oversimplify a subject that deserves better. Horizon tells amazing science stories, unravels mysteries and reveals worlds you've never seen before. 62 seasons (1964–2025) gave the story room most shows never get. What elevates Horizon above most documentary work is a refusal to settle for the easy version of the story. It knows exactly what it is, and does not try to be anything else.

Horizon is the kind of documentary you immediately want to recommend to someone else. The tonal similarities to The World According to Jeff Goldblum are real, though Horizon carves out its own identity quickly. 62 seasons gives the story real room to develop. The access the production gets is remarkable, and the storytelling does full justice to it. Worth watching in order, from the beginning.

Horizon is currently airing new episodes — so there's no better time to catch up before the story moves forward.
