After the new wave of social realist theatre in the 1950s and 1960s, the play fell out of fashion, and was dismissed as an example of outdated bourgeois "drawing room" dramas, but became a staple of regional repertory theatre. Following several successful revivals (including Stephen Daldry's 1992 production for the National Theatre), the play was "rediscovered" and hailed as a damning social criticism of capitalism and middle-class hypocrisy in the manner of the social realist dramas of Shaw and Ibsen. It has been read as a parable about the destruction of Victorian social values and the disintegration of pre-World War I English society, and Goole's final speech has been interpreted variously as a quasi-Christian vision of hell and judgement, and as a socialist manifesto.
