Narrative Summary

The narrative journey in these films is one of inevitable physical corruption. Characters become gateways, hosts, or victims to an alien intelligence or energy that does not obey our reality's laws.

Why These Movies?

Movies in this thread are united by their focus on body horror as a primary vehicle for fear, specifically when linked to cosmic or interdermal origins. They share a high emotional weight driven by the visceral fear of physical violation and a dark tone that accepts the fragility of the human form against incomprehensible forces.
