In Alien: Covenant, a human colony ship's resident nurse android Walter encounters David, an earlier version of himself who survived his own ship's unfortunate crash-landing on an uncharted planet populated by bloodthirsty monsters. The mangled, leggy forms of the pre-Xenomorphs are too, well, alien to connect with, so who do you root for? The robots, of course. While watching Ridley Scott's Alien prequels Prometheus (2012) and Alien: Covenant (2017), it's impossible not to notice their utter disdain for their human characters, and for humans themselves: a failed creation clawing its way out of the sand trap of inevitable extinction.
