Consensus: “Alien: Covenant” is Ridley Scott’s follow up to his highly divisive 2012 film “Prometheus” which was a flick I loved. “Covenant” is both a prequel to “Alien” and a sequel at the same time which was a real weakness. I wished that Scott had picked a theme and stuck with it. As a sci-if, horror flick it is mostly masterful and superbly acted. So in the end I was mixed. I find I enjoyed it best if I think of it as a paralell story instead of a prequel.
