Locker room scene a woman walks in. A man drops his towel bends over and flashes her with his naked rear.

Two men are shown having sex in a very brief and obscured series of flashbacks. No nudity.

Strong discussions of sex (including rape), with graphic detail. In one episode a suspect bluntly and explicitly tells two police officers how his attraction to an underage girl grew over time.

Plenty of instances of violence and murder, as is the show's main theme. Corpses are found in unusual places, and later in the episodes, flashbacks to the murders are shown, usually obscured with shaky camerawork and slow motion.

Around 10 uses of 'f***' per episode, (personal opinion deleted).

SEASON 3: Jesus Christ, Christ and Jesus used as swear words throughout.
