Critic Reviews for There's Someone Inside Your House
Better than average modern slasher. It is derivative, because it is a slasher, by it's very nature it kinda has to be derivative. But it's smarter than it seems, even if it is basic towards the end. There's some good acting and an actual plot for the main characters, even if the killer reveal is cheap, obvious and uninspired. Still, I found myself engrossed instead of just watching while playing on my phone. It's just a slasher, but if you are into horror check it out, Netflix don't usually make good horrors, hopefully this is an indication that is changing.
