Blackadder

Although series 2 ('Elizabethan'), 3 ('Regency'), and 4 ('Great War') were probably better overall, this was the series that introduced Edmund Blackadder to the TV-watching world twenty years ago. In series 1, however, it was Edmund who was spineless and Baldrick who really did have the sense; in subsequent series these roles would be somewhat reversed and the idea then really took off.

I do like series 1 for the following reasons: strong casting aside from Rowan Atkinson, Tony Robinson and Tim McInnerny; this series included Brian Blessed, Robert East as regulars and guests like Peter Cook (brilliant in the very first episode), and Alex Norton (as McAngus). The eagle-eyed will also spot a very young Angus Deayton in the St Leonard's Day episode. While the three following series were sharper and more studio-based (not always a good thing ...) I do think the wild open spaces of The Black Adder helped enormously to get some sense of the Middle Ages into comedy, even if all four series have played havoc with historical fact!
