Constant threat and tension throughout.
The film gets progressively more upsetting, with characters becoming more aggressive and their circumstances becoming more nightmarish.
Masculinity is a theme throughout the film, presenting a cultish dedication to a toxic form of it. Distressing rhetoric endorsing violence and suffering, though from the antagonists.
The film has almost dream-like sequences with disconnected shots inter-spliced with the main footage, creating a sense of unease and confusion. Camera shots, sound effects, and acting feed into the dreamy feeling.
