Kitchen Sink drama is a term used to denote plays that rely on realism to explore domestic social relations. Realism, in British theater, was first experimented with in the late nineteenth and early twentieth century by such playwrights as George Bernard Shaw. This genre attempted to capture the lives of the British upper class in a way that realistically reflected the ordinary drama of ruling class British society.

According to many critics, by the mid-twentieth century the genre of realism had become tired and unimaginative. Osborne’s play returned imagination to the Realist genre by capturing the anger and immediacy of post-war youth culture and the alienation that resulted in the British working classes. Look Back in Anger was able to comment on a range of domestic social dilemmas in this time period. Most importantly, it was able to capture, through the character of Jimmy Porter, the anger of this generation that festered just below the surface of elite British culture.
