Dredd learns that his black-and-white rulebook doesn't necessarily apply when he's assigned to test out a new rookie; she doesn't officially pass, but she behaves above and beyond in other ways. On the other hand, the way that criminal behavior is dealt with in this futuristic world may raise questions about how far the power of the law should extend.
Extreme sci-fi/fantasy violence, with gallons of blood spilled, hundreds of casualties, and thousands of bullets fired (some in detailed slow motion). Characters are smashed by cars, burned alive, and thrown from great heights, splattering on the ground. Other characters are beaten, pummeled, and bloodied; a neck is broken violently. In a few extremely quick flashback shots, characters are skinned alive. Two teens pick up guns to try to kill Dredd; he stuns them before they can cross that line.
In a kind of fantasy sequence, a woman with psychic powers enters a man's mind; he imagines her performing oral sex on him, but the entire thing is brief and is suggested rather than shown. Other very brief, suggestive, but not graphic, erotic images appear in his thoughts. The lead villain is said to have once been a "hooker" and a "prostitute."
Language isn't constant but contains many uses of "f--k," as well as a few uses of "s--t," "motherf---er," "ass," "goddamn" and "bitch." The heroes mostly refrain from using bad language.
The main villain manufactures and sells a (fictitious) illegal street drug called "Slo-Mo," which slows down the user's experiences. Slowed-down "drug trip" scenes are shown throughout the movie. Some teens are seen using the drug. No real-life drugs or alcohol are shown.
