Progressive ideological elements appear through the story's explicit allegorical framing of prejudice against the hybrids as standing in for racism, homophobia, immigration hostility, and neurodiversity struggles, including a bird-man character's failed surgery to appear 'normal' evoking conversion therapy. Director Thomas Cailley has described the mutation as a metaphor for accepting difference, cohabitation in a changing society, and environmental harmony, with the narrative shifting from intimate family dynamics to political questions of rejection versus solidarity.

Casting features a standard French ensemble without race- or gender-swaps of established characters, and diversity among supporting roles remains incidental to the setting rather than foregrounded. Audience and critical reception was largely positive with César wins, though some conservative French commentary criticized the 'vivre ensemble' messaging as tied to migration themes; no widespread 'go woke' backlash emerged.
