The plot of this Alien
prequel was a carefully guarded secret—so carefully guarded, in fact, that not even the movie reveals it. Something about archaeological star maps, a senescent millionaire (Guy Pearce) bankrolling an expedition to a distant moon, green goo that makes people really sick, and the usual antagonistic crew of interstellar explorers (Charlize Theron, Idris Elba, Noomi Rapace, Michael Fassbender). You may feel fussy asking for
a coherent narrative, though, because director Ridley Scott delivers so many of the shocking set pieces that are the real hallmark of the series: pearly
snakes diving down people's throats, vicious cephalopods bursting out of chest cavities, even a frantic abortion sequence in which Rapace, impregnated with some awful critter, undergoes a mechanized C-section inside an automated surgical pod. Production designer Arthur Max deserves a large share of credit too for his blackened lunar catacombs, littered with mollusk-like corpses.
