Sapphire and Steel – The Complete Series

McCallum and Lumley play their "medium atomic weights" with blank style and a few touches of baffled humor, not to mention visual flair in the case of Lumley's blue fashions and occasional glowing eyes. But the lengthy serial format, strictly limited guest casts, and claustrophobic confinement to studio sets tend to mean individual serials straggle on with a great deal of repetition, as six- or eight-part stories seem to take forever to get moving and then resolve. Shot on video, with a few strange 1970s effects (evil follow-spots, floating pillows), this remains prime cult material, though it's hard to sit still for more than one episode at a time. --Kim Newman
