Somewhat grim circumstances, but the movie highlights the way that humans manage to survive under the most difficult circumstances. Challenges people to listen to their instincts, to question following instructions and commands blindly, and to pay attention to their dreams. Also promotes the idea of taking care of the resources that we have -- and to not take them for granted.

The drones kill -- instantly incinerating anyone or anything they're programmed to terminate. Several characters die or are injured (including some major characters), but it's not a bloodbath like War of the Worlds. Explosions, hand-to-hand fights, and lots of danger/peril.

Jack is "assigned" to Victoria both romantically and professionally. They shower together, sleep together, kiss several times, and, in one scene, Victoria seduces Jack by undressing (she's shown nude from the back), jumping into a pool and suggestively inviting him to join her. They're shown kissing passionately (he with his shirt off, she naked, with back and legs visible) underwater. Later, another couple kisses; it's implied that they make love, but nothing is shown.

For most of the movie, language isn't very frequent (though what is heard includes "s--t," "damn," "hell," "goddamn," "oh my God," and "bitch"), but at the very end, there's one memorable use of "f--k."

Despite the future setting, there are references to the New York Yankees and bands/songs such as Pink Floyd, Led Zeppelin, and Procol Harum's "Whiter Shade of Pale."

Jack and Victoria drink with dinner. A character smokes a cigar.
