United 93 is rooted in realism, focusing on the actual events and people involved in the 9/11 tragedy. Characterizations are grounded in the real-life identities and experiences of those on the flight, with little to no evidence of forced representation or ideological meddling in the story. The film prioritizes narrative authenticity over modern ideological themes.

The film portrays American values, bravery, and unity without condescending to traditional morality, religion, or masculinity. Family and faith are treated with respect, reflecting the cultural moment rather than subverting or mocking longstanding traditions.

United 93 avoids ideological finger-wagging or villainization of alternative perspectives. It presents a harrowing situation without slipping into modern ideological uniformity, representing the diversity of those on board without politicizing their stories.
