Crew members are shown in a gauzy wrap that functions as underwear. In Vickers' case, the wrap conforms revealingly to her chest. We also glimpse a large alien humanoid similarly garbed in a loincloth. Shaw and Holloway kiss, and it's implied that they're about to have sex. (She pulls his shirt off; he's on top of her. She's wearing only a robe). Janek and Vickers discuss getting "laid" and she tells him to meet her in her quarters in 10 minutes. Janek crudely tells two male crew members who are lost together, "Try not to bugger each other." 5.6 out of 10.
The opening scene pictures an alien on Earth ingesting what seems to be the same biological agent the Prometheus crew will encounter later. In fast-moving images, his flesh rots, then dissolves entirely. (One of his legs snaps as he collapses into a waterfall.)
A similar fate awaits a human later. David slips a bit of the alien biological agent into a man's drink, and he gets sicker and sicker in the course of a few hours. Eventually his skin turns black and he begins to dissolve, at which point he challenges (begs) Vickers to incinerate him with a flamethrower. She does.
After getting impregnated with a fast-growing human/alien hybrid, Shaw begins screaming, "I want it out … please get it out of me!" Her solution? Climbing into an automated medical pod that she instructs to perform what amounts to an alien abortion. A laser opens her up, and mechanical pincers yank out a squirming alien beastie. Shaw tries to kill it after her massive wound has been stapled shut.
Other characters encounter—to their mortal detriment—a snake-like alien that constricts them and then plunges down their throats. One of those victims later comes back as a hyper-strong reanimated zombie of sorts, and he has to be taken out with gunfire and a flamethrower.
Shaw is caught in a ferocious sandstorm that pummels her against the ship; she also gets slammed around a great deal the last 20 minutes of the film. The Engineer that David awakens rips his David's head off and kills Weyland with it, punches Ford, crushing her sternum. A security guard, Jackson, attempts to shoot it, but the Engineer grabs him and throws him into a nearby wall, breaking his spine. The alien that Shaw "births" captures and plunges into the mouth of the Engineer. Later, the dying engineer gives birth to a Deacon (a Xenomorph hybrid).
Vickers is crushed by a falling piece of spaceship. Three characters are killed in an explosion. There's a fistfight. 7.5 out of 10.
Profanity: 3 "f" words (1 is obscured by static) and 10 "s" words. Other words include around 9 "hells," 4 "damns," 3 uses of "laid," 2 "S.O.B.'s" and 1 use of "piss," 1 use of "bugger" (used sexually) and 1 use of "bastard." The V sign is used twice. Religious exclamations and profanities include at least: 14 uses of "Oh, God," 10 of "Oh, my God," 5 of "Goddamn," 3 each of "Jesus Christ" and "Jesus," 2 of "For God's sake," and 1 use each of "God," "So help me God" and "Oh, Jesus." 5.3 out of 10.
Substance Use: Two scenes show Holloway with a bottle of alcohol, and he's clearly drunk. Other crew members drink, too.
Fifield figures out how to smoke inside a spacesuit's helmet, and it's implied to be marijuana. Shaw pops pain pills after her impromptu Cesarean. 4.5 out of 10.
Conclusion: "Prometheus" is a brilliant prequel to the Alien franchise, bringing new characters, a great story, a decent script and fantastic performances. While this film appears to create more questions than it answers, this is nonetheless a great film. I give this film 8.3 out of 10.
