First, Prometheus and Nostromo are great spaceship names. The computer and video surveillance technology is so dated and primitive here in what is supposed to be 30 years further in the future. You run into that problem whenever prequel movies are made decades after the original, but I found it difficult to get past the late 70’s effects. The crew’s relationships are developed a little more, since there aren’t as many characters. The sets on the planet where the distress call originated do look creepy and, having seen Prometheus first, I now know a lot more than the characters do. The ship’s captain (played by Skerritt) appears quite heroic for awhile when they first encounter the Alien, then Weaver, as Ripley, steps up as that new type of intelligent and tough survivor. A woman. The twist involving the crew’s doctor was good. I did not see it coming, although it appears to be a common theme in Ridley Scott science fiction. There is a lot of hot steam escaping all over the ship to obscure what we are able to see as the chase escalates. Scott edits so many flash cuts of the Alien to keep it mysterious. The movie is heavier on the horror than the sci-fi in the end.
