Common Sense Note
Parents need to know that this movie (based on the same-named video game) is full of incessant, mostly mindless action (though not too much blood), much of which seems to be designed to showcase girls in bikinis and underwear. In fact, there's a fair amount of sex-related content for a movie aimed at kids -- including brief profile shots of a woman's breasts, characters embracing and flirting in bed, the assumption that two women are lesbians, and more. There's also some implied drinking, as well as several uses of words like "s--t," "ass," and "hell."
Sexual
Content
Women wear bikinis and/or underwear, showing lots of cleavage; men appear in underwear, too. Christie first appears in the shower, then a towel as she battles intruders (she slips her panties on to distract them, eventually tossing her bra into the air, which then falls onto her naked form in slow motion, accompanied by brief profile shots of her breasts -- but they're suggestive rather than explicit). Max and Christie embrace in bed and make flirty talk (the movie then cuts to a presumably post-sex scene in bed); Zack "comes on" to Tina in hot tub; she flirts, then leaves with his clothes (he gets out naked, covering his genitals). Seeing two women in bed prompts a father to assume that they're lesbian lovers. Battle between two women takes place in rain and slow motion (wet T-shirt effect); Christie and Max kiss passionately; closing kiss inspires Tina to tell a couple to "get a room."
Violence
Video-gamey violence includes kicks, karate chops, punches, body slams, flips, falls from great heights, sword fights, crotch grabs and crotch kicks, needle stabs/pricks, head-butts, bites, breaking bones (with crackly sound effects), eye gougings, martial arts weapons (stars, poles, etc.), and explosions. Pirates appear with guns but don't use them. Father and daughter fight it out in a river; two girls fighting throw each other around in the mud and rain. The island explodes at the end (in slow motion, of course).
Language
Several uses of "s--t," plus "ass," "hell," and "son of a b--" (it's cut off in mid-utterance).
Social
Behavior
Inane motives are the primary offense here, though the fact that just about everyone joins in the ongoing melee means there are no moral or intellectual alternatives.
Consumerism
One big promotion for the video game it's based on.
Drugs / Tobacco /
Alcohol
Characters drink what looks to be beer, champagne, and wine.
