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


Depends what ratings are intended to do - if they are just to be informative for potential viewers then the kind of system you propose sounds good.
But, if the main purpose is to legally restrict access based on age, such ratings wouldn’t really do the job.
Plus, of course, there’s quite a range within each category - language could mean something as innocuous as “bum”, or something as deeply offensive as “Belgium” or “Barbara Streisand”.
I suppose you could have age ratings for each subcategory - L18, V12, N0, S0, D15, but it’d start to get complicated pretty fast. Plus, presumably, whatever the highest of those ratings was would still be the overall rating. At which point we’re back where we started.
VNS-17
Descrbes what the film contains and a recommended age.
Yeah, true. I think I maybe misunderstood your OP - I thought you were looking to replace ages ratings entirely, as opposed to combining them with something more informative. Something like that could be useful, for sure.
