Ridley Scott steers further from the mindbending but distracting mythology of 2012's Prometheus and tries to recapture the claustrophobic horror of his 1979 original Alien. The crew of a colony ship, bound for a remote planet, stumbles across a seemingly perfect world. Unfortunately, it's the old home planet of the Engineers, the alien giants who created the space age superweapon known as the Xenomorphs. It isn't long before the crew is on the receiving end of some acid-blooded alien carnage. Like Prometheus before it, this prequel has got way too many ideas, but at least it delivers on the chestbursting thrills. Michael Fassbender, Billy Crudup, Danny McBride, Katherine Waterston, Demián Bichir and Jussie Smollett are among the rather doomed cast.122 minutes R.
