abstract="<p>The Motion Picture Association of America created the parental guidance for children under age 13 years (PG-13) movie rating in 1984 to “strongly” caution parents about content that may not be suited for children of that age. According to that industry-supported group, “There may be depictions of violence in a PG-13 movie, but generally not both realistic and extreme or persistent violence,” (www.filmratings.com). Unlike PG-13 films, which are open to all, those rated R can only be seen in theaters by those under 17 years who are accompanied by a parent or other adult.</p> <p>Language: en</p>",
