Alien (1979)

(Some spoilers ahead.) An extremely solid classic horror/thriller. I always put off watching it because I didn't know if it would be nearly as good as it was claimed to be. And although the sudden twist with the appearance of the robot was, I felt, a little bit silly, the parts with the alien were well crafted and pretty much terrifying. Now I have to decide whether or not I want to see any of the sequels. 4 stars.
