Star Trek: Enterprise (2001–2005)

Star Trek: Enterprise is left-leaning as its central narrative arc focuses on humanity's challenging journey to overcome xenophobia and establish a multi-species alliance through diplomacy and shared values, ultimately leading to the Federation. While acknowledging the need for strength and individual heroism, these elements serve the broader progressive ideals of cooperation and understanding.

Star Trek: Enterprise features visible diversity within its main cast, including prominent roles for minority characters, though these are original roles rather than explicit recasting of traditional characters. The narrative explores themes of interspecies relations and human challenges in first contact, but it does not explicitly critique or negatively portray traditional identities.
