The movie has underlying messages about self-reliance, honor, and character -- but since the film takes place in the world of illegal street-fighting, there's a disconnect between the characters' purpose and the sometimes-brutal action. New York's neighborhoods are depicted using broad ethnic stereotypes -- Brooklyn is full of Russian Jews, Chinatown full of caricatured Asian gangsters, the Bronx teeming with cliched Latinos, etc.
Non-stop bare-knuckle brawling -- including grappling, punching, wrestling moves, kicks, punches, and more. Characters are shown bloodied and beaten after fights. Some gunplay; a supporting character is shot in the ear. The infamous "sleeper hold" is used repeatedly.
Some kissing and cleavage; some suggestive talk about transvestites. Kissing leads to what must be sex; the deed isn't shown, but it's implied via a cut to characters cuddling and getting dressed.
Language includes "ass," "s--t," "dick," "nuts," "bitch," "oh my God," and "a--hole." References are made to "white boys," and the "N" word is used once.
Brands mentioned or featured on screen include Mercedes, Everlast, and International House of Pancakes.
Characters drink hard liquor and beer and smoke cigars and cigarettes. Characters go to bars. "Crackhead" is used as an insult.
