For much of the period covered here the literature of England was dogged by an all-pervading sense of failure and decline. In Stevenson's analysis, a "misplaced nostalgia" impeded the progress of English drama, fiction and especially poetry. Philip Larkin mourned an "England gone", and he cast a long shadow over English verse. "English literature was never more static than under the influence of the Movement," says Stevenson. "If the later 20th century proved a difficult period for poetry, it was in large measure because it took so long to realise this, and move on."
