Look Back in Anger is a play that appeared in a time of crucial transition from Britain's Victorian past into the modern twentieth century. Jimmy's rage and anger is his expression of pent-up emotion and his need for life in a world that has become listless and uninteresting. That anger became a symbol of the rebellion against the political and social malaise of British culture. His anger is destructive to those around him and the psychological violence of the play received a great deal of criticism. Critics today agree, however, that the play is central to an understanding of British life in the twentieth century and, thus, a crucial piece of literature in the British canon.
