Another is 'Blade Runner' (the novel Do Androids Dream of Electric Sheep? by Philip K. Dick). It has some adult - themed elements such as complex moral questions around what it means to be human, along with some gritty and noir - like situations that could lead to an R - rating. It presents a future world where androids are almost indistinguishable from humans, and the moral and ethical implications are deeply explored.
