Monstrosity and mystery are two things director Ridley Scott has mastered over the years and this is his masterpiece. From the opening shot to the finale, you're in for not just a thrill ride, but a well-written prose of poetry and art in one. The dark brooding atmosphere with the well-designed sets amplified with the great performances from the cast, especially Sigourney Weaver's memorable work, all melding together seamless and flawlessly. And who could ever forget the creature, created with costuming and puppetry with grace unparalleled for sheer terror especially the crew members most unfortunate to encounter it. There are many great jump scenes that still hold up along with the dated technology which only amplifies the fear factor, and ironically makes it more realistic and terrifying. For best results make sure you watch on an empty stomach and with the lights off.
