The Cabin in the Woods (2011) starts as a classic “teens in a remote cabin” horror, before twisting into a meta-nightmare where secret technicians manipulate events as part of a ritual apocalypse. Cleverly blending slasher tropes with monster mayhem and satire, it has become a cult favorite that deconstructs the entire horror genre.

A group of kids go to a remote cabin in the woods where their fate is unknowingly controlled by technicians as part of a world-wide conspiracy where all horror movie clichés are revealed to be part of an elaborate sacrifice ritual.
