Aileen is a prostitute and becomes a serial killer but throughout the movie you learn what shes been through in her past and Charlize Theron manages to play her role so well, that you kinda feel sorry for Aileen. Its a very moving film, based on a true story. Theron deserved her Oscar.
A dark tale based on the true story of Aileen Wuornos, one of America’s first female serial killers. Wuornos had a difficult and cruel childhood plagued by abuse and drug use in Michigan. She became a prostitute by the age of thirteen, the same year she became pregnant. She eventually moved to Florida where she began earning a living as a highway prostitute—servicing the desires of semi-truck drivers. The tale focuses on the nine month period between 1989 and 1990, during which Wuornos had a lesbian relationship with a woman named Selby. And during that very same time, she also began murdering her clientele in order to get money without using sex. This turned the tables on a rather common phenomena of female highway prostitutes being the victims of serial killers—instead Wuornos, herself, carried out the deeds of a cold-blooded killer.
