Director James Cameron did the improbable. He followed a highly regarded science fiction horror film with a sequel that lives up to it. Aliens has more action and adrenaline and less horror than the original, but is no less of a gripping and downright exhausting experience. The film is, thus, a noteworthy accomplishment in the science fiction, horror, and action genres. Like the original, the intensity and gore in Aliens make it advisable for the faint of heart to stay away.
