One of the primary strengths of Acrimony is its unflinching portrayal of gaslighting and emotional manipulation. Robert, the film's antagonist, is a master manipulator who uses his charm and charisma to control Melinda's perceptions of reality. He denies his own infidelities, tells Melinda she is overreacting, and isolates her from her friends and family. These tactics are disturbingly familiar to survivors of emotional abuse, and Perry's depiction of them is both harrowing and accurate.
