– There’s Someone Inside Your House review does not contain spoilers –
There’s Someone Inside Your House is a true-blue slasher film. If you’re a fan of movies that cut open people and stalk and harass them, only to murder them within the next minute, this is going to be a great addition to your list.
The movie opens with a murder, as most slashers do, to let us know exactly what we’re getting into. Sure, it might be similar to Scream or I Know What You Did Last Summer, but there’s something new that the movie adds. The killer wears their victim’s masks while killing them. It might sound pretty stupid, but oh boy, it’s so fricking creepy.

Also, severing the Achilles tendon? Yeah, gnarly. The kills are the best part of the movie, so if you’re easily disgusted, this probably isn’t the right deal for you. However, for everyone else, this is gonna be a fun watch.
The characters are insufferable. There are several cliques in the school to which Makani and her friends go, and of course, there’s the b*tch ones who start getting murdered. It’s honestly expected because of how insufferable they are. You cheer as they get murdered (which is a weird feeling to have if I’m being honest). How badly do people have to f- up so that people want them to end up in a ditch?

The character motivations, too, are pretty well chalked out. You might think everyone is a culprit, like how nasty seniors are in schools. The bullying and the mistreatment make you feel like everyone’s got a motive to do something horrible. Don’t worry though, there are ample twists and turns in the movie to keep you guessing. You aren’t figuring out things that easily!
The actors in There’s Someone Inside Your House are really good. They are relatable, funny and hella fun. The “secrets party” is amazing to watch and the memorabilia into bongs? Yes, that’s what I wanna watch. Our protagonists are people whom you connect with and want to stay alive. But who’s the real killer? Is it someone among them? Is it the obvious subject? Well, you have to watch the movie to find that out!
Summing up: There’s Someone Inside Your House
