Alien (1979)

The original Alien film from 1979 is a terrific sci-fi horror movie.  The pace is slow, but it builds suspense and has some genuinely scary moments.  

Rating: A

I like the sequel, Aliens, even better for its faster pace.

The scene is iconic and important to the movie. It also goes by quickly. The film quickly switches from relaxed and sexual to sheer terror as Ripley is surprised by the alien monster. Ripley in her underwear feels more vulnerable, but she finds a way to fight back demonstrating that she is a strong character.
