The film critiques human exceptionalism, the notion that humans are separate from and superior to the natural world. The characters' expedition into the Shimmer is motivated by a desire to understand and contain the anomaly, reflecting a hubristic assumption of human control over nature. However, as they journey deeper into the Shimmer, they encounter a realm where human exceptionalism is challenged, and the boundaries between human and non-human, self and other, begin to blur.
