A horror feature based on Josh Malerman's novel 'Incidents Around the House.' This film follows Bela, a young girl who is painfully aware of the problems between her parents that threaten her family's happiness. However, Bela has a friend, 'Other Mommy'. A mysterious entity that helps Bela, but has sinister intentions of wanting to take possession of her.
Horror is the genre that is really having a moment right now. In 2026, we've been treated to an absolutely stacked roster of films like Obsession, Hokum, Resident Evil or 28 Years Later: The Bone Temple. But Other Mommy is not like the rest; it's not even punching near films like Undertone. Rob Savage's latest feature is a painful watch that lacks a sense of pacing, decimates its own sense of tension and barely holds a semblance of narrative together between a couple of decent scare motifs. I liked that the stakes for this film started high, that Other Mommy had a tangible presence from the beginning. The fact that there was a physical aspect to this haunting of Bela made it all the more unnerving. Some of those very early sequences in which she steadily made herself known were fairly frightening and disturbing. Even later, there are some great moments with Bela being transported to the ocean or Other Mommy being backlit by the lighthouse at night.
This movie starts with high stakes and the sinister presence established, which I thoroughly enjoyed. Unfortunately, what I should have also realised was that this would be a precursor to an absolutely insane sense of pace. This movie is rushing without purpose, often chasing us along to the next big scare, but rarely feeling like it was lugging the story forward at all. The moment Other Mommy becomes a problem, she remains a problem for the duration of the film. We jump from one house to the next, from a fast food restaurant playground to the eccentric grandmother's house. The film is a chase: stay ahead of the demon that will inevitably just show up once again. In the background, there's family tension that feels poorly explored and unbearably vague. You wonder if this is thematic of impending divorce, or if it's about the mother's infidelity. Ultimately, we get an unusual confessional about the way their family dynamic came to be and an admission that the mother never wanted Bela. This is an important climactic reveal, but the work hasn't been done to get us here. But this is a film that often struggles with tone. Sometimes there will be an absolutely horrendous moment, like Bela being attacked during an anniversary party, only for us to suddenly cut to guests being politely and gently waved off as they slowly depart the household. The script lacks a real sense of itself, and that often leads to a feature that feels comical and not so scary. Watching a squad of ghost detectors rock up to grandma's mansion is a trope that really jumps the shark. Dichen Lachman is a great performer, but the moment we got a séance table involved, I had a feeling we'd be watching one of the weakest scenes of the feature. Even the conclusion struggles to make sense, often sidestepping Bela's confrontation and then twisting the end of Other Mommy into a sucker punch that will probably strike you in the funny bone.
I think some people might have been less than impressed with some of the visual choices in Other Mommy, but I think it's probably the one shining facet at play. There's a very clear intention here to try some inventive scare moments, positioning the camera to really go on a journey and experience each moment differently. I particularly loved the ceiling balloon scene with Other Kelvin (a role that is played superbly and all too briefly by Sean Kaufman). The visual effects are a real mixed bag, but I think that also adds value. It's entirely too difficult to predict how Other Mommy is going to present. Sometimes she's serpentine, others a shadow demon and I loved that imposed image of her under the water as we tilt into the final act. If there is a technical element that really let the feature down it's the score, which is your classic nails against the chalkboard stuff.
Jessica Chastain comfortably gives the best performance, though this falls short of some of her titanic performances in the past. It's also no surprise that Chastain is having the most fun when she gets to play a demonic entity that is from beyond this world. Arabella Olivia Clark leads this film as Bela and is really quite versatile as a young actress. I would have liked to see the final confrontation scene brought down a notch, but the film was well and truly off the rails by that point. Jay Duplass is clearly the weak link in this family unit as the meek Dad who slowly has to learn to fight for his family, and Karen Allen doesn't really flesh out the wise grandma stereotype. Uncle Frank (Moayed) is a side character with a ton of charisma; I could have done with more of him. It would have been stronger if the tension between Chastain, Moayed and Duplass had sincerely been allowed to come to a head.
A script that had no business being viewed as complete. I would give Other Mommy a 2.5/10.
