In the end of Philip K. Dick's book, the replicants hide in John Isidore's flat, where he owns a single apartment, and whose silence scares him like a monster; and John Isidore, who's labeled as "special" (this label exists because of nuclear radiations), cries because the replicants cut a spiders' legs and because he can do nothing about it (they're too strong).

So at some point, a female replicant carelessly bombs people living in a giant dump from a drone while having a nails manucure and I thought that if Ridley Scott was a good producer he would do something interesting at the end of the movie
