The crux of the plotline focuses on Jennifer's transformation into a succubus. Jennifer's metamorphosis is the direct result of the demonic sacrifice she was victim to in the chronological beginning of the story. An upcoming indie rock band, "Low Shoulder," makes a sacrifice to Satan in order to gain fame; however, the most important detail in this sacrifice lies in the fact that it must be a virginal offering. Because Jennifer is scarified based on the conception that she is a virgin when she is indeed not one, the sacrifice turns into a case of demonic transference.
In a larger context, Jennifer's lack of purity is what ultimately saves her from being sold to Satan, and this salvation is a reversal of moral messaging found in so much of the mainstream media regarding purity. Interestingly, at the beginning of the film, Needy remarks that she is unable to find salvation within prison, saying, "They tell me everything will be okay if I just accept Jesus Christ into my heart. I say the words, but nothing ever happens. Nobody comes back. Nobody gets off the cross" (Cody 1). This quotation underscores the film's rejection of commonplace Christian values, which draws comparison to Cody's corresponding rejection of beliefs regarding virginity.
The screenplay also includes several satirical remarks about rape culture that was dominant in early aughts culture. The idolization of the band "Low Shoulder" following the assault on Jennifer is representative of the widespread acceptance violent men had in society. "Low Shoulder's" song about Jennifer's assault actually became widely praised, which echos the lack of accountability for violence against women and the feeling of entrapment on felt by victims. In an article for Vox, Cody says, "That movie [Jennifer's Body] was very much about the issues that women face and about the feeling of being powerless and about the feeling of wanting to turn the tables."
The sharp contrast found in Jennifer's sacrificing scene is also notable: the band members were completely dissonant to the pain they were inflicting, and the sounds of their laughter rang in tandem to the blood-curdling screams of Jennifer. The band members fail to simply name Jennifer correctly, again underscoring their believed superiority, which underscores Cody's perception of the society in which she lived. The brutality of this scene, Jennifer's suffering, and "Low Shoulder's" complete dehumanization of Jennifer shows a central conflict that parallels one that may be understood to be dominate in 2000/10s society.
Jennifer's character at the beginning of the film is also noteworthy. The audience of 2000/10's society may not find it easy to find sympathy for Jennifer's sacrifice; she is not the kind of person that is easy to see as a victim. In fact, Jennifer exemplifies most of what is considered morally wrong, especially for women. She is mean, aloof, self-centered, sexually uninhibited -- the opposite of someone to take pity on. But this fact is what makes Jennifer's character and Cody's writing so dynamic: Cody highlights the visceral pain Jennifer feels during her representative sacrifice to convince the viewer that there is never an excuse for the violence that women are subjected to by men. Jennifer was not kind, but she did not deserve what happened to her because no woman does.
This kind of argument is generally agreed upon in modern day discourse, but that was not the case in 2000/10s society, and Cody explains this with her writing.
