Deepstar Six is a unique sci-fi because it breaks the tradition of having sci-fi's set in space. Deepstar Six is about an underwater navy base that comes under attack from a sea monster that threatens the base and the lives of those in it. This movie has influenced the movie "Deep Blue Sea" (1999),with the theme of an underwater base and a creature that threatens them. Deepstar has submarines instead of the standard of spaceships in sci-fi's which is one of the reasons this movie is a refreshing change from other sci-fi's.
