The psychological thriller aspect of the film is expertly crafted, keeping the audience on edge as Michelle tries to uncover the truth. She experiences strange occurrences and begins to doubt Emmett's claims, suspecting that Ben might be involved in a sinister plot. The cat-and-mouse game between the characters creates an sense of unease, making it difficult to discern friend from foe.

The sound design is equally impressive, with the sound of creaking metal, the hum of generators, and the ominous silence outside the bunker all contributing to the sense of unease.

The film's visuals and sound design play a crucial role in creating an immersive experience. The camerawork is often claustrophobic and intimate, placing the audience in Michelle's shoes. The use of lighting and shadows adds to the tension, creating an eerie atmosphere.
