According to Rick Kogan, "Aliens" demonstrated science-fiction horror could still be entertaining after many poorly-received "Alien"-derived films. Dave Kehr and Richard Schickel called it a rare sequel which surpassed the original, and Kehr appreciated the action used to develop the characters. Schickel wrote the film had evolved from "Alien", giving Weaver new emotional depths to explore. Jay Scott said the talented Cameron had redefined the war film, combining "Rambo" with "Star Wars". Kogan agreed Cameron possessed a knack for action pacing and excitement, but Kehr believed Cameron pushed some elements beyond believability.
