Leave the World Behind heavily foregrounds identity dynamics over organic character development. Casting choices and dialogue often seem driven by modern representation checklists, making personalities secondary to demographic traits. The plot at times contorts itself to foreground ideological points, undercutting narrative cohesion or realism when it might conflict with the chosen themes.

The film frequently paints traditional family, masculinity, and established norms as either problematic or relics of the past. If anything, it seems to relish portraying these elements as ill-equipped for crises, while more modern or reimagined roles are showcased as heroic or insightful.

Alternative or dissenting worldviews are mostly sidelined or represented via awkward caricatures, if at all. There’s little genuine debate; the film steers all major characters toward a cheerleading section for current ideological trends.
