"Other Mommy" posted a solid $27.5 million domestic opening despite dismal reviews and a rare D+ CinemaScore, the weakest audience grade in years, signaling weak word-of-mouth that typically triggers steep second-weekend drops in horror. Analysts expect at least a 70% decline as the low-budget Blumhouse title faces intensifying competition from holdovers like "Resident Evil" and upcoming seasonal scares. Comparable recent releases with C+ scores fell around 64%, underscoring how poor reception compresses theatrical legs even when initial interest from the Jessica Chastain-led premise delivers a strong debut. Traders are monitoring early tracking and exit polls for confirmation of front-loaded performance ahead of the October 16–18 frame.
