Common Sense Note
Parents need to know that this intense 3-D adventure movie set in the world of cave diving was produced (though not written or directed) by James Cameron and feels very much like a smaller-scale version of one of his epics -- like Titanic and Avatar -- and is just as focused on spectacle. There's plenty of heavy language (including many uses of "f--k" and "s--t"), and the violence includes fighting and blood, plus gruesome drownings and dead bodies -- all of which is amplified by the 3-D. You can also expect some drinking and smoking and a little innuendo.
One character brings his girlfriend to the caves; she wears revealing clothing from time to time. Also a small amount of sexual innuendo.
Characters die in horrible ways, from bashing their heads on rocks to drowning. Viewers see bloated corpses and blood, and characters make gurgling sounds as they choke on blood. One character catches on fire. Characters also fight and squabble every so often, and there's one knockdown brawl with fatalities.
Heavy language includes many uses of both "f--k" and "s--t." Also "ass" "a--hole," "c--k," "damn," "goddamn," "oh my God," "hell," and more. One character raises a middle finger.
The movie's major theme involves the struggle to overcome the odds and survive. The characters must learn to work together and solve new problems at every turn. The secondary theme involves an emotionally distant father and his son finding a connection. But not everyone learns a lesson here ... or even survives.
Drugs / Tobacco /
A minor character is briefly seen smoking. A major character brings a bottle of hard liquor down into the cave; characters occasionally drink from it during the movie's first third, but no one gets drunk.
