A debut film from playwright Bess Wohl that focuses on a French lifestyle blogger named Jo, who experiences postpartum depression and postpartum psychosis. After giving birth to her baby Ruby, Jo begins to feel that her newborn is hostile towards her and she is unable to shake the feeling. The film keeps a close first-person perspective, showing Jo's increasingly paranoid mindset through shock cuts and hallucinatory elements, leaving the audience to question what is real and what is not. The movie's intent is to address the struggles that many new mothers face, but the constant use of horror tropes like pot boiling on the stove and repetitive "did I just dream it or did it really happen" moments drain away the power from the underlying message.
The film's real bite comes from its cultural observation of entitled girl boss culture, the "pick me girl" turned new mom, and the private citizen acting like a celebrity/expert, but these elements are presented more as background noise rather than the main event. Ultimately, "Baby Ruby" falls short of fully exploring these important cultural issues and instead focuses on the horror and melodramatic elements of Jo's postpartum struggles.
