The sci-fi genre is one of the most varied in storytelling, offering everything from the mind-bending twists of Christopher Nolan's Inception to the more thought-provoking themes of Children of Men. But the best sci-fi movies find a way to balance weightier thematics with grandiose set pieces, and few have done this better than Ridley Scott's Blade Runner, or even Denis Villeneuve's sequel. Both movies did a fantastic job of exploring the nature of AI and the thin line between created and natural life while also delivering some unforgettable set pieces and production design.
