Other Mommy (2026) Movie Review
Other Mommy is a supernatural horror film starring Jessica Chastain in a chilling dual role as a mother and a mysterious entity that imitates her.
The story follows young Bela, whose frightening encounter with the presence turns her home into a place of uncertainty and fear.
Chastain delivers a compelling performance, while the eerie atmosphere creates several unsettling moments.
However, uneven pacing, confusing storytelling, and predictable horror techniques weaken the overall experience.
Although the film explores disturbing family dynamics and childhood fears, its execution may disappoint some horror fans.
Still, its creepy premise offers moments of genuine suspense.
CR Rating: 7/10.
