Casting fits the source descriptions with no race or gender swaps of established characters. Lisbeth's punk appearance, piercings, tattoos, bisexuality, and vigilante revenge against her abusive guardian and other violent men form a core character trait from the source material, not a modern addition, delivering a strong unconventional female lead whose traits are justified by the original text. Central themes of misogyny and violence against women are integrated into the thriller plot as direct drivers of the mystery and revenge narrative, echoing the book's original Swedish title without overt lectures or systemic-oppression framing. Author intent stays focused on anti-misogyny journalism rather than contemporary activism, keeping progressive elements subordinate to entertainment and plot momentum rather than elevating them as the primary message.
