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.

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.

...well-made, well-acted and should keep couch-bound sleuths guessing until the end...

There's Someone Inside Your House is intermittently effective, but ultimately unremarkable, and it feels like a product of its time in disappointing ways.

2.5/5

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.

There’s Someone Inside Your House is not meant to be a parody of slasher films, but it does not have any entertaining elements.

1.5/5

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.

It starts strongly and has a clever visual hook in the killer's masks, which turn identity, exposure and shame into part of the threat. The teen setting works, the pace is solid and Sydney Park gives the film a convincing center. The main problem is predictability. By the halfway point I had already worked out who the killer was, and once that happened the mystery lost much of its tension. The film also relies too heavily on familiar slasher rules: when a suspect is pushed too obviously, experienced viewers automatically know to look elsewhere. That is frustrating because the premise offered room to subvert those expectations. Still, it remains entertaining, has a few effective set pieces and never becomes boring. A decent teen slasher with some good ideas, but not enough nerve to break the genre rules it clearly knows so well.

Lame plot, obvious killer (the straight white male friend of the group) heavy handed “messaging” that what? All white people are privileged and deserve to die. Lame kills and not enough kills. Way too many survivors. Just a bad movie

Predictable woke messaging crammed into a forgettable slasher.

NOTHING LIKE THE BOOK. They changed so many pivotal scenes and butchered some of the most fundamental characters to the plot. Absolutely DO NOT recommend.
