The US government reported that there were more alien invasions in the 1990's than any other decade. Of course, this was only in the movies. When it comes to scariest sci-fi movies of the 90s, fans enjoyed them because they were both frightening and satisfying. The combination of fear and science fiction proved to do well in the box office, but what did it do to our minds? Movies like Deep Blue Sea made our weariness of sharks even greater, while the 1990 film Hardware, made us second guess all of the ever-evolving technology that is all around us. Classic sci-fi horror films have a way of making us wonder, "Could this happen to us?" which is sometimes the most terrifying of all. And of course, as technology improves, so does the believability, which makes the sci-fi movies of the 90s even more terrifying than their predecessors.
