Alexandre Freire Duarte analyzes the film Lamb in a theological review

In a review for Voz Portucalense, Alexandre Freire Duarte examines the film Lamb, noting that the main character, played by Neeson, is a lay brother in a religious congregation dedicated to educating disadvantaged children and youth. Duarte observes that while the character is not a priest, his conduct is markedly priestly, particularly during a tragic final scene involving a baptism.

The review describes the drama as a dark and disturbing film that uses visual and musical styles to create a sense of sinister isolation. Duarte suggests the film explores the complexities of service, noting that while Christian service is rooted in the transcendent, it can lead to utopian behaviors that result in terrible consequences.
