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.

Rated: 1/5

...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.

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

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.

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

SPOILER WARNING: Definitely would not recommend this watch, I read the book before watching the movie and (the book) was absolutely amazing but the movie lacked in pretty much every aspect. There was poor acting, poorly written murders, also didn’t try to match any of the characters to the descriptions written in the book (I know this is not always easy but it’s like the only character they tried to match with the book was Makani). Also they added the part where Ollie did a background check making him seem like a bad guy when she revealed this later on in the book.

Rated 0.5 out of 5 stars
