Orson Welles Great Mysteries (1973), a British mystery/horror anthology series which turned out to be surprisingly very good indeed and at times nicely creepy.
Harry O (1974), a delightfully quirky series which quickly established itself as one of my all-time favourite private eye series.
Voyagers! (1982), an American kids’ time travel science fiction series which is much more fun than I expected.
The Human Jungle (1963), an all-but-forgotten British series about a psychiatrist. Insanely melodramatic and often ludicrously far-fetched (and not a crime series as one might have expected) but it does star Herbert Lom which is always a bonus.
I’ve also revisited some old favourites, such as The Invaders (which made me realise that I’d never actually seen the second season).
And Return of the Saint (1978-79), which I think is one of the more successful attempts to revive a classic series, keeping a surprising amount of the feel of the original.
The most popular posts of 2020 with readers of this blog have been:
Sheena Queen of the Jungle (1955), a very lightweight good-natured jungle girl adventure series.
The Saint in Europe, and on TV, a review of both the Leslie Charteris collection of short stories and the 1960s TV episodes adapted from those stories.
The Green Hornet (1966-67), somewhat in the Batman mode but less zany and much darker.
