Ask any fan of 1960s spy show ‘The Avengers’ and they’ll all tell you the same thing – series four was the point where it started to go seriously bonkers.

Do you remember when British television used to be good? I mean consistently good?

Good stuff like ‘The Avengers’, not Z-list celeb-reality tat or auditions for Lloyd-Webber’s latest West End ‘hit’. I’m talking G.O.O.D.
