LVNSD would be much more informative than "Rated R," or, "PG-13."

• L - Language
• V - Violence
• N - Nudity
• S - Sex
• D - Drug use
• B - Blasphemy

Let's include recommended age at the end, so theaters can know whom to exclude (legal reasons):

Family Guy LVNDB-18

Dexter's Lab V-8

Looney Toons VD-8

Telly Tubbies 0
