This is the best Sci Fi/ Horror movie ever made. Mind boggling that it was made in 1979. It is one of those seamlessly perfect movies where there are no wasted scenes or dialogue. Even the score and special effects are nearly flawless. If I had never seen this before and you told me that it was made in 2009 I would believe you (other than the obvious youth of the actors ). It has aged better than any movie I have ever seen, a remarkable achievement for a sci fi flick. I love the way we are treated to about an hour and ten minutes of first rate believable drama and science fiction before we get to the alien hunting down and killing the crew one at a time. But we have to realize that even that tired formula was brand new in 1979. This movie was made the same year as John Carpenter's original"Haloween ". We have to remember that back then we actually jumped out of our seats every time the killer jumped out of the shadows ! And of course the classic ending with a female hero. This could be the tightest most perfect movie ever made or at least it is in my book..
