There is something wonderfully sad and ephemeral about comedy. Consider, for example, the situation comedy and film franchise Sex and the City (1998). When Sex and the City arrived on TV screens, it reached out to a wide audience by challenging established attitudes towards sex and gender. Indeed, when Sex and the City first started, women (though sexually liberated) were expected to be less interested in sex than men. However, by the time Sex and the City graduated to cinema screens, cultural attitudes had moved on and it was now accepted that women could be just as crass and emotionally stunted as men. Thus, what began life as a critique of traditional values ended its life as a chest-thumping celebration of the status quo. The history of comedy is littered with examples of films and series that simply ran out of cultural currency as the attitudes they critiqued or embodied came to seem either more or less oppressive.
An excellent example of a series left culturally isolated by changing social attitudes is Andrew Davies and Bernadette Davis’s Game On.
