Under the Dome

The narrative's central hero, Barbie, is a mysterious white male with a dark past, but the primary antagonists, Big Jim Rennie and his son Junior Rennie, are also white males, preventing a complete vilification of whiteness. The casting includes a Latina actress as Deputy Linda Esquivel, who holds a position of authority. A key subplot revolves around a new family unit consisting of an interracial lesbian couple and their daughter, characters created specifically for the television adaptation to comment on social debates. This demonstrates a moderate, intentional application of diversity and intersectionality within the primary cast.

The central premise frames the American small town of Chester's Mill as a deeply flawed society, immediately exposing its inner corruption, drug trade, violence, and dark secrets upon the crisis. The town's rapid descent into mob rule and fascism under Big Jim Rennie presents the home culture as fundamentally weak and prone to collapse without external rules. The overarching philosophical theme for the season is described as 'faith, fear and fascism,' directly critiquing the inherent character of the secluded American community.

Female characters like journalist Julia Shumway and Deputy Linda Esquivel are prominent, active, and competent leaders in the crisis. The two main villains are Big Jim Rennie and Junior Rennie, who embody toxic masculinity through tyrannical power-grabs, kidnapping, and psychological abuse. This opposition frames corrupt power and violence as a distinctly male failing. One character expresses explicit anti-natalist sentiment, stating a reluctance to bring a baby into the world inside the dome, viewing motherhood as undesirable in a time of crisis.

The characters Alice and Carolyn, a married lesbian couple, were a deliberate inclusion in the TV series who did not exist in the original book. They are presented as a stable, functional, and interracial family unit, which is noted by an executive producer as a conscious effort to participate in the 'very relevant debate today about gay couples raising children.' One of the couple’s daughters, Norrie, becomes one of the central teenage characters in the dome’s mystery, centering a non-traditional family at the heart of the narrative’s main quest.

The primary human villain, Big Jim Rennie, explicitly uses religious language and claims of being 'chosen by divine providence to lead the town' to justify his authoritarian control and murderous actions. His corrupt and self-serving fascism is directly linked to a distorted or false sense of religious destiny. This narrative choice, coupled with the seasonal theme of linking 'faith' with 'fascism,' portrays a traditional faith-based moral framework as the root of the town's evil and oppression.
