In the 1968 film *Rosemary’s Baby*, the audience's emotional investment is sharply divided between the victimized protagonist and a circle of perpetrators who exploit her. This division is fueled by the film’s use of **gaslighting** and the betrayal of the most basic social and domestic trusts.
### The Character the Audience Roots For: **Rosemary Woodhouse**
Audiences almost universally sympathize with and root for Rosemary because she represents a total loss of agency in the face of overwhelming, organized manipulation.
* **Vulnerability and Isolation:** From the start, Rosemary is depicted as a kind, gentle, and somewhat naive woman whose primary goal is to start a family. As the film progresses, her support systems are systematically stripped away. When her friend Hutch dies under suspicious circumstances, she is left entirely alone in a world that refuses to believe her.
* **Physical Suffering:** Unlike many horror protagonists who face external monsters, Rosemary’s horror is internal. She experiences excruciating, "knifelike" pains during her pregnancy, which her husband and doctor dismiss as "normal." The audience roots for her to find relief and to have her pain validated.
* **The "Gaslighting" Experience:** Much of the rooting interest comes from the audience's shared perspective. Because the film stays close to Rosemary's point of view, the audience feels her mounting paranoia. Every time she is told she is "imagining things" or "being hysterical," the audience—who sees the truth—feels a desperate urge for her to escape and be proven right.
* **Final Act Resolve:** In the final act, when she finally pieces together the truth, her frantic attempt to escape to Dr. Hill and her subsequent recapture create a high-stakes moment where the audience is fully "in her corner," hoping for a miracle that never comes.
### The Characters the Audience Roots Against
#### **1. Guy Woodhouse (The Ultimate Traitor)**
While the Castevets are the "villains," Guy is often the character the audience loathes most because his betrayal is personal and intimate.
* **Selling His Wife:** Guy’s "root against" factor stems from his decision to trade Rosemary’s body and their child’s soul for his acting career. The audience sees him as a narcissist who prioritizes a Broadway role over his wife's safety and consent.
* **Active Betrayal:** He is the one who gives her the drugged chocolate mousse (the "moussecat") and then lies to her the next morning, claiming he had sex with her while she was unconscious because he "didn't want to miss the night." This act of marital rape—and his role as an accessory to her actual rape by the devil—makes him irredeemable.
* **Gaslighting:** Guy is the primary architect of Rosemary’s psychological torture. He constantly undermines her instincts and forces her to stay with the sinister Dr. Sapirstein, effectively "fencing her in" for the coven.
#### **2. Minnie and Roman Castevet (The Puppet Masters)**
The Castevets are rooted against because they represent a predatory subversion of the "friendly neighbor" archetype.
* **Invasive Presence:** Minnie’s overbearing behavior—asking the price of everything, forcing Rosemary to drink her "vitamin" shakes, and giving her the foul-smelling tannis root necklace—creates a sense of violation that the audience finds repulsive.
* **Sinister Charisma:** Roman is rooted against for his cold, calculated manipulation. He identifies Guy’s vanity and exploits it. The audience's dislike is fueled by the contrast between their "sweet elderly couple" facade and their goal of bringing the Antichrist into the world.
#### **3. Dr. Sapirstein**
Dr. Sapirstein is a character the audience roots against because he violates the sacred trust between doctor and patient.
* **Medical Malpractice:** He instructs Rosemary to stop reading books and listening to friends, effectively cutting off her access to information. By ignoring her physical agony and insisting on Minnie’s herbal drinks, he uses his professional authority to facilitate her abuse.
