Aliens (1986)

A recent unexpected TV viewing left me wondering if this is the Citizen Kane of Science Fiction Horror movies. Near perfect film making on every level from James Cameron, on a roll that would include Terminators 1&2 and the most perfect film of the lot. Even the sound effects or the machine guns are sublime. Full marks for production design, screenplay, effects that haven't dated, developed side characters that pack a memorable punch, unbearable building tension, iconic lines and an almost unheard of lead acting Oscar nomination for it's equally unusual female action lead, Sigourney Weaver as Ripley. Hugely influential from video games to any film where a state of the art military force is hopelessly out of its depth and packed with fascinating subtext like having warring mothers as both antagonist and protagonist. A perfect 10/10.
