XXY centers identity, in this case, exploring intersex experience and gender fluidity, as the primary driver of the narrative. While the approach is sensitive, some viewers may feel issues of identity somewhat overshadow traditional character development, as relationships and setting serve primarily the ideological theme. That said, it avoids cartoonish depictions or “flawless” leads.

The film challenges traditional views of gender, sexuality, and the family unit, questioning established roles and expectations. It depicts parents, societal norms, and masculine archetypes as sources of tension and misunderstanding. This can be interpreted as a pretty substantial subversion of traditional cultural foundations, especially considering its 2007 release date.

Alternative viewpoints are mainly shown as either oppressive or out of touch, rather than as valid perspectives deserving much sympathy. The adults embody discomfort or ignorance, and the film doesn’t offer much space for pluralistic debate about gender identity, it's generally one-sided in its sympathy.
