"No futuristic plastic fantastic technology. Metal takes over, and dominates the look and sound of the film. Sigourney Weaver’s wonderful, resourceful Ripley doesn’t just continue the tough-woman role but transforms and refines it until she out-Rambos Rambo, succeeding where the military cannot. And of course there are the Marines—the “mechanized infantry” of Robert Heinlein’s Starship Troopers, which Cameron boldly adopted a decade before Paul Verhoeven’s film and dropped into Aliens about forty minutes in. We have references to a “bug hunt,” getting the shakes before a drop, female pilots, cameras mounted on the Marines so leaders behind the lines can see what the troopers on the point are seeing. Cameron clearly loved Heinlein’s novel and found a way to film it by dovetailing it neatly into his sequel to someone else’s film of someone else’s vision."
