Out of curiosity, what does these G, PG, etc really mean?
"G" means "general audience", good for all ages
"PG" means "Parental Guidance", some questionable content, not for tiny kids.
"PG-13" means "Parental Guidance 13", not recomended for those under 13
"R" means "Restriced" , very adult content not recomended for anyone under 17.
"NC-17" not sure what the N stands for. No one under 17 permited without an adult. This is the rating that was relatively recently institued to replace "X", because the X rating had become known for porn.
"X" was originaly meant for what NC-17 is today. It became a stigma afterthe porn industry used it as a selling point, and no movie house would dare let a real movie be rated this.
