Thoughtful things are said about humanity's foibles through the course of the show; however, female characters are treated in sexist ways.
Graphic violence: shootings, stabbings, a throat slit, torture. Usually violence involves robots, but since they bleed and seem to be in pain and look just like "real" humans, this distinction is mostly unimportant. A robot's face is blown off by gunshot in one gory scene; characters are shot point-blank and scream and groan piteously while "dying." An implied rape takes place offscreen after a robot is dragged shrieking by the hair; a prostitute has sex in a scene where it's unclear if she's consented. Robots are "operated on" in gory scenes that may frighten sensitive viewers.
A prostitute has sex in a scene in which it's unclear if she's consented. Both male and female robots are shown nude from the rear and front, with breasts and genitals visible. An orgy is depicted.
Infrequent cursing, but what's said often comes in moments of violence and fear: "f--k," "s--t," "ass," "hell." A female robot is called a "little bitch."
Anti-consumerist messages: Unappealing tourists boast about how much they spent before taking pleasure in dominating robots.
Characters drink brown liquor and smoke in frequent saloon scenes. Characters on a work break smoke cigarettes together.
