"Meanness is big in "Alien Resurrection." It's hard to remember a more coarse, obscenely violent movie. The "fun" starts right away with open-chest surgery shown in up-close, disgustingly graphic detail (with Brad Dourif as an icky doctor). The scene is the birth of a baby alien from under Ripley's ribs. Whoever said that surgery was the next pornography was right. In the course of the film, viewers get treated to aliens feeding on guts, brains and heads, all shown in splatter-movie fashion. And there are constant references to predatory sex acts. That popular '90s phrase "viewer discretion advised" is definitely applicable."
