Unrestricted

• G - General Audiences - All ages admitted. There is no content that would be objectionable to most parents. Very mild language may exist, including words such as "heck", "moron", "dumb", "rats", "darn", "fart", "burp", "idiot", "crud", "jerk" or "stupid".
• PG - Parental Guidance Suggested - Some material may not be suitable for children. These films may contain some mild language, crude humor, thematic elements, sexual themes, scary moments and/or violence. No drug content is present. The word commonly known as the "F-word" or "F-bomb" generally was not heard in pre-1984 "PG" films. There are a few exceptions to this rule. A few racial insults may also be heard.
• PG-13 - Parents Strongly Cautioned - Some material may be inappropriate for children under 13. Stories given this rating may contain sexual content, sexual themes, some strong language and innuendo, humor, mature themes, political themes, terror and/or intense action violence. The "F-bomb" can be used only once in the story. This is the minimum rating at which drug content is present; marijuana is the maximum use for this rating, with a few exceptions. While PG-13 stories usually have more profanity than PG stories, this is not necessarily the case. A story that is given a PG-13 rating due to profane language and/or racial insults is given this rating because it contains more of these elements than a PG rating would permit. A story rated PG-13 for "intense violence" is given this rating if blood is present in a violent way. 

 Restricted

• R - Restricted -  An R-rated story may have more blood, gore, drug use, or graphic sexuality than a PG-13 story would admit.
• NC-17 - These stories contain a lot of graphic violence, sex, aberrational behavior, drug abuse, strong language, or any other elements which, when present, most parents would consider too strong and therefore off-limits for viewing by their children and teens. NC-17 does not necessarily mean obscene or pornographic in the oft-accepted or legal meaning of those words. 

Others

• NR or Not Rated - NR means the story is not yet rated.
