Space Opera is defined as "colorful, dramatic, large-scale science fiction adventure, competently and sometimes beautifully written, usually focused on a sympathetic, heroic central character and plot action, and usually set in the relatively distant future, and in space or on other worlds, characteristically optimistic in tone. It often deals with war, piracy, military virtues, and very large-scale action, large stakes." by David G. Hartwell and Kathryn Cramer.
