Space: 1999 has built a real following in the US on Amazon Prime Video and fuboTV, and in the UK on ITVX Premium among viewers who want their sci-fi to think as hard as it looks. Every one of its 2 seasons holds up. Its 7/10 TMDB score, built from 160 ratings, reflects a title that consistently delivers. Martin Landau sets the tone, and the world-building does the rest. There is no real reason to keep putting it off — it is right there on Amazon Prime Video.

Whatever else is competing for your attention this week, Space: 1999 is worth clearing space for. What makes Space: 1999 work is that the ideas never crowd out the people having them. The crew of Moonbase Alpha must struggle to survive when a massive explosion throws the Moon from orbit into deep space. Martin Landau and Barbara Bain lead a cast that makes the ambitious moments land. The series ran for 2 seasons (1975–1977), building a story that gave its audience time to invest properly. The rules of Space: 1999's world are consistent enough that the big swings never feel like cheating. It knows exactly what it is, and does not try to be anything else.

Viewers burned by ambitious sci-fi that could not sustain its premise should give Space: 1999 a chance. Viewers who responded to Star Trek: The Next Generation will find a lot to like here too. Best experienced as a single, sustained watch if your schedule allows. Watch for Martin Landau in particular — the performance elevates the material. Satisfying on multiple levels.

Space: 1999 wrapped up in 1977, created by Sylvia Anderson and Gerry Anderson — and 2 seasons are available to watch from start to finish.
