"The Unnatural," a season six episode of The X-Files written and directed by David Duchovny, uses a 1947 Roswell setting to explore humanity, alienation, and American mythology through the lens of Negro League baseball. The story follows Josh Exley, an alien bounty hunter who abandons his mission to live among humans, highlighting the episode's themes of empathy and the search for identity. This widely acclaimed, experimental installment departs from the series' typical, darker tone to offer a poignant meditation on what it means to be human.
