Other Mommy parents guide: Is your kid ready for this child-centered horror movie?

Other Mommy crept into the public consciousness over the summer with a scary trailer playing ahead of The Odyssey in theaters nationwide.

From the title and the bit of body horror teased in that clip alone, many grown-ups saw similarities to Coraline , in which a little girl battles with a deformed doppelgänger of her own mother.

But before you think this means Other Mommy would be a good pick for a spooky season night out with your scary-story-loving kid, let's break down what you might want to know first.

Light spoilers ahead for Other Mommy.

What's Other Mommy about? Credit: Universal Pictures Based on Josh Malerman's New York Times best-selling novel Incidents Around the House , Other Mommy centers on Bela (Arabella Olivia Clark), a 7-year-old girl who has been talking to an entity she calls "other mommy." As you might guess, Other Mommy (Jessica Chastain) looks a lot like Bela's real mommy, Ursula (also Jessica Chastain).

This makes for several troubling sequences where Bela isn't sure if she's talking to her mom or the entity.

When Ursula and Bela's dad, Russ (Jay Duplass), become aware of Other Mommy and her magical ability to kidnap their daughter to far-off locations in the blink of an eye, they try desperately to stop it.

But along the way, there will be casualties and lots of jump scares.

Part of the power Other Mommy has in the film comes from Bela's fear that her parents' might split up.

While she's very close with her stay-at-home father, Daddo (as she calls Russ), Bela views her mother with a suspicion that Ursula would rather be anywhere else than in their home.

This divide between daughter and mother is how Other Mother becomes such a compelling temptation.

She's never too tired to play.

She always smiles.
