Consequently, when Mexican writers introduce incest, they are not usually writing erotica. They are writing horror or tragedy. Early Mexican cinema (the Época de Oro, 1930s–1950s) used incest as a symbol of moral decay in rural communities. Films like "La Mujer del Puerto" (1934) and "Victims of Sin" used hidden sibling relationships or father-daughter abuse as catalysts for redemption or ruin. The incest was rarely romanticized; it was a secret that destroyed everyone it touched.
