Krypton takes familiar Superman mythology and significantly alters established character backgrounds, notably race-swapping key characters like Zod for modern representation. While the show attempts to build its own narrative, some viewers may find these changes driven more by current social agendas than storytelling necessity, which slightly undermines character realism and depth.

Traditional gender roles are selectively subverted, and family dynamics on Krypton are depicted as corrupted and in need of progressive reform. Masculinity is occasionally portrayed as problematic or tied to the old regime, with female and minority characters given heroic prominence, possibly at the expense of established traditions.

Alternative worldviews, particularly traditional or conservative perspectives, are largely absent except as traits of authoritarian villains. There's a clear ideological uniformity, with most main heroes sharing similarly modern values, and little space for genuine internal debate about those values.
