Common Sense Note
Parents need to know that this violent sci-fi action sequel is loud and gory, with multiple exploding chests and heads; lots of mangling, penetrating, and acid-burning; bloody injuries; screaming children; and gross-out assaults. There's a bit of cleavage, a scene that lingers on a girl's skimpy-underwear-clad bottom, a bit of drinking, and references to being stoned. Language includes repeated "f--k"s, plus other profanity.
Some women's T-shirts show cleavage. Brief flirtation between teenagers leads to her invitation to "go swimming": she removes her top to reveal lacy black bra and boy-short underpants; they kiss passionately, interrupted first by bullies, then aliens.
Typical Aliens-style violence includes chests exploding, teeth ripping flesh, acidic blood burning human faces. Standard Predator business includes hunting prey, shooting with lasers. Several scenes stand out: A small boy watches his father get attacked by an alien and cries in terror; the father's arm falls off, and after the boy is also attacked, both of their chests explode to "birth" toothy, hissy little aliens. A small girl sees her father assaulted by an alien who crashes through her bedroom window and rips him up. An alien enters the pregnancy ward, sucks babies out of women, and implants its own babies inside; a later scene shows their bellies bursting open bloodily to reveal little aliens. Other images include a space ship crashing, heads blown off or shot through with Alien's penetrating jaw, a girl pinned to a wall by Predator's throwing star, bullies hitting and kicking Ricky, shooting at the aliens that produces blood and burning flesh, and blood all over. Alien-Predator fights feature punching, kicking, biting, shooting, throwing bodies against/through walls. Nuclear explosion kills some protagonists.
Repeated uses of "f--k" (two with "mother"), plus other profanity, including "hell," "s--t," "damn," "dickhead," "a--hole," "bitch," "slut," and "ass." A joke about a "sausage-lover's pizza" is meant to suggest that the boy who ordered it is gay.
Bullies pick on Ricky; ex-con Dallas is selfless and brave; mother/Iraq war veteran Kelly is selfless; the sheriff makes some wrong decisions; federal government representative is dishonest.
