The revisionist Western (also called the anti-Western, sometimes revisionist antiwestern) is a sub-genre of the Western film. Designated a post-classical variation of the traditional Western, the revisionist subverts the myth and romance of the traditional by means of character development and realism to present a less simplistic view of life in the "Old West". While the traditional Western always embodies a clear boundary between good and evil, the revisionist Western does not. Revisionist themes have existed since the early 20th century, but it was not until 1968, when the Hays Code restrictions were relaxed, that revisionism finally supplanted the traditional. Although many earlier Westerns are labelled revisionist, the distinction between them is often blurred by variable themes and plot devices. Some are labelled psychological Westerns which is closely related to and sometimes overlaps with the psychological drama and psychological thriller genres because of their focus on character at the expense of the action and thrills that predominate in the traditional. Other revisionist films, in which action and adventure remain prominent, are labelled Indian Westerns or Outlaw/Gunfighter Westerns because, instead of the traditional hero, the protagonist is a Native American, an outlaw or a gunfighter. The Spaghetti Westerns of the 1960s, not bound by the Hays Code, were strongly revisionist by presenting morally ambiguous storylines featuring an anti-hero or a sympathetic villain. From 1969 onwards, revisionism has prevailed in Western film production. Concept The traditional Western typically features a strong male lead character, often a lawman or cavalry officer, who takes direct action on behalf of supposedly civilized people against those deemed to be uncivilised. The former are portrayed as honest townsfolk or travelers, the latter as outlaws or hostile Native Americans. In the revisionist Western, the traditional format and themes are subverted by such devices as the Native American protagonist; strong female characters; the outlaw protagonist; plots that are pre-eminently concerned with survival in a wild environment; or the presentation of a morally ambiguous storyline without definite heroes, these often featuring the so-called anti-hero or a sympathetic villain. The object is to blur the traditionally clear boundaries between "right" and "wrong" (the "good guy" against the "bad guy") by emphasising the need for survival amidst ambiguity. The traditional Western treats characters in simplistic terms as good or bad with minimal character development. The psychological Western, which began in the 1940s and was hugely popular through the 1950s and 1960s, prioritizes
