The film's central thesis critiques appearance-based discrimination and social inequality, highlighting the suffering caused by societal superficiality and advocating for empathy and standing up against bullying, which aligns with progressive social justice themes.

The animated series 'Lookism' features casting that is consistent with its South Korean origin, utilizing Korean voice actors for its characters, which is considered traditional for its cultural context. The narrative critically explores themes of appearance-based discrimination and social hierarchy, offering a critique of societal superficiality. However, it does not explicitly frame traditional identities negatively as a central theme, nor does it center on Western-defined DEI themes like race or gender identity in its primary critique.
