Top Critic Reviews

Fresh: Charlize Theron gives her finest performance yet in the unlikely role of serial killer Aileen Wuornos in this riveting depiction of the Florida prostitute's decent into madness.

- Cole Smithey,, Thursday, June 24, 2010

Fresh: The film's worth seeing for Charlize Theorn's stunning performance, based on complete physical and psychological transformation, but as a dramatic feature, it lacks an interesting perspective and is underpopulated in terms of characters.

A great acting performance from Charlize Theron is what stand out the most. Telling the true story and sad decline of a prostitute turned serial killer. I think that fact it's based on a true story makes it more interesting, however the story as such is quite straight forward.

Charlize Theron thoroughly deserved her Oscar for this one as it wasn?t just her make-up that made her convincing, she really got into the part!
