The technology of "Prometheus"
"Prometheus" is supposed to be a prequel to the "Alien" movies, but the technology is all wrong. Touch screens, holograms, futuristic looking computers... something must have happened to devolve computer technology to the DOS-based text-only screens of the 1979 movie. You should not make a prequel with technology that is much more advanced than the movie that is supposed to follow it. Continuity matters.
