Alien
Watching Alien, the mega classic science fiction horror blockbuster from 1979 that spawned a slew of sequels and is probably one of the most watched films in history, is a grueling, terrifying, sometimes sickening experience. I compare it a little to being lost in the bowels of some fossilized insect, the doom proffered by the Alien "Mother" lurking around every dark, dripping, desiccated, or, alternately slime-corroded corridor. It is dark, white-knuckled terror at the end, reminiscent of Scott's later Blade Runner (1982) wherein Harrison Ford must contend with his own personal Alien Queen Mother--in the form of Roy Batty (Rutger Hauer).
