Despite the initial appearance of an action film, Blade Runner operates on an unusually rich number of dramatic levels. As with much of the cyberpunk genre, it owes a large debt to film noir, containing and exploring such conventions as the femme fatale, a Chandleresque first-person narration in the Theatrical Version, and the questionable moral outlook of the hero — extended here to include even the literal humanity of the hero, as well as the usual dark and shadowy cinematography.
