Alien: Covenant, like the many offerings of that benevolent hydra known as the Marvel Cinematic Universe, depends to no small extent on the foreknowledge of its filmic predecessors, both directed by Ridley Scott: the landmark sci-fi horror touchstoneAlien, of course, but more obviously the unjustly maligned Prometheus from 2012. Fittingly, it borrows strands of DNA (as it were) liberally from both, melding the basic structure of both with the grimy, generally no-frills mode of the former and the sense of wonder and existential doubt of the latter. The result is something slightly uncanny, as initially shocking as the notably CGI aliens (a far cry from the hulking suit of the original film), but thrilling and hard-hitting all the same.
What sets Alien: Covenant apart from its forbears is its method for unleashing hell. Functionally speaking, it takes a two-pronged approach, conveniently divided into two halves. The first concerns the various crew members of the Covenant, a deep-space colony mission diverted by a mysterious transmission issuing from a heretofore unknown planet that seems completely suitable for life, including acting captain Christopher (Billy Crudup), second-in-command Daniels (Katherine Waterston), chief pilot Tennessee (Danny McBride), and android Walter (Michael Fassbender). The second picks up neatly after various survivors of the initial alien attack are assisted by David (Fassbender again), the android figure from Prometheus who has been dwelling on the hostile planet for ten years.
