Entertainment / Literature / Closure: (Latin clausura, 'a closing') Closure has two common meanings. First, it means a sense of completion or finality at the conclusion of play or narrative work--especially a feeling in the audience that all the problems have been resolved satisfactorily. Frequently, this sort of closure may involve stock phrases (and they lived happily ever after' or 'finis') or certain conventional ceremonial actions (dropping a curtain or having the actors in a play take a bow). The narrative may reveal the solution of the primary problem(s) driving the plot, the death of a major character (especially the antagonist, the protagonist's romantic interest or even the protagonist herself), or careful denouement. An example of extended denouement as closure occurs in George Eliot's Middlemarch, in which the author carefully explains what happened in later years to each character in the novel. Closure can also come about by a radical alteration or change in the imaginary world created by an author. For instance, in J. R. R. Tolkien's The Lord of the Rings, much of the closure to the saga comes from the departure of the elves and wizards, who sail across the sea, leaving the world of human men and women forever, an act which apparently causes magic to fade. Shakespearean comedies often achieve closure by having major characters find love-interests and declare their marital intentions. Other more experimental forms of literature and poetry may achieve closure by 'circular structure,' in which the poem or story ends by coming back to the narrative's original starting spot, or by returning a similar situation to what was found at the beginning of the tale. See discussion under denouement. Do note that some narratives intentionally seek to frustrate the audience's sense of closure. Examples of literature that reject conventions of closure include cliffhanger serials (see above), which reject normal closure in an attempt to gain returning audiences. Many postmodern narratives influenced by existential philosophy, on the other hand, reject closure as too 'simplistic' and 'artificial' in comparison with the complexities of human living.
