Critics Consensus

A likable cast and strong set pieces give There's Someone Inside Your House a lift, but they're outweighed by its messily misguided story.

Wenlei Ma News.com.au All its failings could be semi-forgiven if There's Someone Inside Your House did the one thing that was promised on the box - be frightening. Rated: 1/5 Nov 2, 2021 Full Review Stephen Romei The Australian ...well-made, well-acted and should keep couch-bound sleuths guessing until the end... Oct 15, 2021 Full Review Roxana Hadadi Polygon There's Someone Inside Your House is intermittently effective, but ultimately unremarkable, and it feels like a product of its time in disappointing ways. Oct 9, 2021 Full Review Paul Lê Tales from the Paulside While it is easy to compare this to the admittedly more unique slashers before it, There’s Someone Inside Your House at the very least does everything on its own terms. It is not capitalizing on nostalgia or trapped in the past. Rated: 2.5/5 Jul 23, 2023 Full Review Nuha Hassan Hear Us Scream There’s Someone Inside Your House is not meant to be a parody of slasher films, but it does not have any entertaining elements. Jul 20, 2023 Full Review Keith Garlington Keith & the Movies It’s slasher formula 101 – introduce the killer’s fodder (most often a group of insufferable teens) and then slice them, carve them, chop them, and impale them one by one. That’s this movie in a nutshell. Rated: 1.5/5 Aug 17, 2022 Full Review Read all reviews

Not great at reviewing but i enjoyed it Rated 4 out of 5 stars 10/12/25 Full Review J F Great thriller!!! Loved how I was left wandering the whole time who the killer was! Rated 5 out of 5 stars 09/26/25 Full Review ShawBarrie A Predictable ending, but not too heavy on the I’m better than you theme. Rated 2.5 out of 5 stars 09/20/25 Full Review Calvin T Damn it's not a 19%.....at least it's a watchable movie but that's about it Rated 2.5 out of 5 stars 09/13/25 Full Review Waniya S The gore was good, it wasn’t extreme but still it was good. And the romance 🤭🤭🤭 also if there’s someone in your house RUN OUTSIDE 🤦‍♀️ Rated 4 out of 5 stars 08/21/25 Full Review Read all reviews
