Common Sense Note
Parents need to know that the relentless, ravenous clawed monsters iin Aliens, the sequel to Alien, are likely to give small kids (and others) nightmares. It's even more violent than the original. Besides the rerun of the grisly moment when embryonic aliens burst out of people (in reality and in dream scenes), we also see quick cuts of victims seared with acid, getting set on fire, and blowing themselves up with a grenade. Gunfire, bombs, and flamethrowers are directed at the aliens. Most disturbing of all -- or, at least, the most nakedly manipulative -- is the perpetual threat of ghastly violence/death/contamination directed at a frightened, screaming little girl. There's also a plethora of swearing and lots of adoring fondling of guns and high-powered weapons.
Indistinct glimpses of pin-up pictures in a locker room. Some mildly suggestive banter between co-ed Marines.
Mostly in quick flashes, but still severe, as human characters are splashed with acid, torched with fire, or have little aliens bursting out of them. One man is literally torn in half, with the qualifier that "he" is an android, not human, with beige-colored blood and viscera. Gunfire, bombs, and flamethrowers are directed at the aliens. Much of the violence and lethal danger is threatened against a small child.
"F--k" and "a--hole" in soldierly banter and anger.
A mothering instinct/motherly love drives both Ripley and the queen alien. Technology doesn't always guarantee sueriority in combat, as shown by gung-ho Marines charging into tunnels with high-powered guns only to get shredded to pieces by hordes of an enemy that keeps on coming -- director James Cameron's metaphor for the Vietnam War.
