The film lacks explicit evidence of LGBTQ+ characters or narratives. The plot focuses on a singular protagonist's psychological descent within a professional medical setting.

While the central protagonist is a male physician, the cast includes prominent female actors like Leandra Leal and Cláudia Abreu. This suggests a significant female presence within the ensemble.

Set in Rio de Janeiro, the film utilizes a diverse Brazilian socio-cultural landscape. The cast features various established Brazilian actors, offering a more heterogeneous representation than many Western productions.

The narrative critiques institutional structures by focusing on the failures of state-run hospitals. It disrupts traditional portrayals of state institutions by highlighting systemic dysfunction and bureaucratic instability.

The protagonist's loss of reality touches on mental health instability. However, it is unclear if this is a nuanced exploration or merely a plot device used to heighten horror.
