Sapphire & Steel - Wikipedia

Any fans? I watched the series on YouTube, being much too young to have caught it earlier (Also, I don't think it was ever popular here in the States). This show is genius, and I recommend it to sci-fi and fantasy fans alike. I like the idea that the origins of the main characters are pretty much just as mysterious as the in-universe entity of time itself. I believe it was made to compete with Doctor Who. Steel is memorably Spock-like, and Joanna Lumley (Sapphire) is lovely. All the episodes, as well as a documentary about the series, can be found on YouTube.
