The film lacks prominent LGBTQ+ characters or non-cisnormative identities. The central romantic arc between Jacob and Emma adheres to traditional heteronormative structures.

Miss Peregrine serves as a strong, authoritative leader and strategist rather than a domestic figure. While female characters possess significant agency, the central conflict still revolves around the male protagonist's journey.

The cast is largely homogeneous, reflecting a Western European demographic consistent with the 1943 setting. Peculiarity is defined by supernatural abilities rather than ethnic or racial identity.

The story follows a traditional moral framework centered on guardianship and community preservation. It uses an outsider motif to subtly deconstruct societal standards of normalcy.

Supernatural peculiarities serve as a metaphor for neurodivergence and physical difference. Characters use these traits as sources of agency to navigate their world rather than being portrayed as burdens.
