"A sequel to director Ridley Scott's "Alien" was inevitable, of course. This traditional horror movie set in outer space simply made too darn much money for the studio to simply let it stand alone. Surprisingly, when director James Cameron took over, he was determined to make a different movie rather than merely rehash the first. Thus, "Aliens" was adventurous, taking the story in new and exciting directions as an action-adventure yarn instead of another horror movie. Indeed, several critics feel "Aliens" is better than "Alien.""
