The House of the Head (A Creepshow short on SHUDDER)

Genre: Horror
Rating: TV-MA (M)
Warnings: Mild Gore, Mild Body Horror

This has a few jumpscares, slow building tension and a genuine sense of threat. Like the viewer ourselves, the protagonist is a girl watching the haunting unfold in her dolls' house. She tries to help them, adding a policeman doll, but it just gets worse. 

Some gore and body horror for the dolls later, as the dolls and the doll haunted head move on their own and bleed seemingly real blood. A very simple concept plays out very creepily and even poses a real threat in a nice surprise. It's still more thrilling than scary, but it is enjoyably spooky.

Just as her dolls and the haunted head doll break the fourth wall, looking at her and reacting to her from the very beginning, this short implies a fourth wall break too. The head appears in her dollhouse for seemingly no reason. As the threat escalates, it threatens the girl too. The girl seeing the horror play out in her dollhouse is a mirror for the viewer watching the horror play out in films. When the head becomes a danger to her, breaking the fourth wall, it becomes a danger to us in that mirror metaphor.

And, it seems to say, who knows what could suddenly appear or happen in your dolls house? Or your real house? The House of the Head is a good little spook.
