Parasitized

Parasitized is a 2011 psychological horror film directed by Jonathan Glatzer and starring Adam Paul, Lou Taylor Pucci, and Mickey Rourke. The film follows a young man named Jack who becomes increasingly paranoid and believes he is being stalked and attacked by a mysterious entity. As his mental state deteriorates, his relationships with his girlfriend and his father suffer. The film explores themes of mental illness, addiction, and the subjective nature of reality.

The plot centers on Jack's descent into madness, fueled by what he perceives as a parasitic infestation. He becomes obsessed with ridding himself of this unseen invader, leading to increasingly erratic and self-destructive behavior. His girlfriend attempts to help him, but his paranoia extends to her, pushing her away. His father, a former detective, tries to intervene, but struggles to understand the depth of Jack's delusion. The film blurs the lines between Jack's internal struggle and external events, leaving the audience to question what is real.

Parasitized received mixed reviews from critics. Some praised its unsettling atmosphere and strong performances, particularly from Adam Paul as the tormented protagonist. Others found the film's narrative confusing and its reliance on ambiguity to be frustrating. The film's slow-burn pacing and bleak outlook were also points of contention. Despite the varied reception, it has gained a cult following among fans of psychological horror.
