While 'Miller's Girl' focuses primarily on character dynamics and power imbalances, it does at times lean heavily into topical social issues. Some character choices appear influenced more by contemporary identity themes than narrative necessity. However, the film retains a core story about obsession and manipulation, rather than becoming entirely about ideology.

The film questions classic student-teacher boundaries and explores gender dynamics, presenting certain traditional roles in a critical light. Themes of masculine authority are scrutinized, and conventional morality gets challenged, but it's more interested in uncomfortable ambiguity than outright condemnation of tradition.

Most characters seem to share modern attitudes concerning power and identity, with little sincere voice given to more traditional viewpoints. Some alternative perspectives are acknowledged, but the narrative largely supports only one side of the debate.
