Blade Runner initially underperformed in North American theaters and polarized critics; some praised its thematic complexity and visuals, while others critiqued its slow pacing and lack of action. The film's soundtrack, composed by Vangelis, was nominated in 1982 for a BAFTA and a Golden Globe as best original score. Blade Runner later became a cult film, and has since come to be regarded as one of the greatest science fiction films. Hailed for its production design depicting a high-tech but decaying future, the film is often regarded as both a leading example of neo-noir cinema and a foundational work of the cyberpunk genre. It has influenced many science fiction films, video games, anime, and television series. It also brought the work of Dick to Hollywood's attention and led to several film adaptations of his works. In 1993, it was selected for preservation in the National Film Registry by the Library of Congress.
