Grundy(1980)

Grundy is a British sitcom starring Harry H. Corbett as Leonard Grundy, a puritanical newsagent navigating life after divorce. Grundy rails against the permissive society of the era, forming an unlikely friendship with the wife of the man who ran off with his own spouse. The show was originally slated for late 1979 but faced delays due to an industrial dispute and Corbett's health issues, ultimately premiering in 1980. The premise mines comedy from Grundy's clash between old-fashioned morality and the changing social landscape around him, anchored by Corbett's sharp performance as the disapproving, principled protagonist caught between worlds.
