Restricted movies contain adult themes in abundance. So much so that anyone under 17 requires a guardian to get into the movie. They can contain any of the following: violence, drug abuse, sexuality, profanity, nudity, or other adult themes (among other things). An R rating constitutes a strong warning toward parents to investigate the content of a movie more thoroughly before they take their children to see them. Most R rated movies are considered to be too adult oriented for the average minor to view. R rated movies, as well as PG-13 rated movies usually contain a brief description of why they are given the rating they are. A typical listing would look something like this: Rated R for pervasive graphic violence, brief nudity, and some strong language. The modifiers like pervasive, brief, and some, are intended to let a parent know how much of a given element to expect in a movie.
