The movie's main theme is revenge, and although there are a few hints of redemption at the end, it sticks close to that motif, with the main characters killing without repercussions.
Two huge gunfights with shooting and dead bodies, though not much blood is shown outside of minor injuries. A frozen corpse is shown. Characters are shot in the head and shot at close range. Other characters are shot by long-range rifle. A character is hanged with a rope. A character is briefly tortured -- tied up and covered with hungry rats. A bloody ear is shown after an operation. A woman is briefly held hostage during a shootout. A car crashes into a building.
A minor character is shown having sex with a prostitute (she demands her money afterward). Very little nudity is shown: The woman wears her bra, and though she doesn't have underwear on, she covers herself. The two main characters kiss on two occasions.
"F--k" is used several times, in various permutations, throughout the movie. "S--t" is also used a few times. "Bitch" is used once.
Tupperware is mentioned a few times. A delivery service that resembles FedEx is used but is fictionalized for the movie.
One scene takes place in an illegal drug facility, with piles of cocaine shown. Almost all of the main characters smoke cigarettes at least once. The main female character drinks a beer in a restaurant.
