Sweet Tooth often foregrounds identity themes, with a focus on hybrid children as stand-ins for real-world minorities. Diverse casting and certain characters seem selected more for contemporary representation than organic fit, at times sidelining nuanced character growth. The allegory leans heavy-handed, occasionally making the story feel more like a vehicle for ideology than pure adventure.

The show tends to question traditional family, masculinity, and even religious morality through a very modern lens. Fatherhood is portrayed ambiguously, and traditional structures are either broken down or depicted as part of the old, failed world. Familiar cultural backbones get a distinct, critical reimagining.

Dissenting perspectives within the show are rarely fleshed out outside of villain caricatures. Almost all characters, especially protagonists and sympathetic figures, operate from nearly the same modern worldview, leaving little room for alternate viewpoints or traditional ideas to be taken seriously.
