Drastic and unrealistic ideas accomplish very little.

Concerned families will still want simple labels so that they can know at a glance if they don't want their 13yo seeing certain movies.

I didn't know anyone paid attention to the specific content list next the the letter grade.

Separating movies by tiny indicators of general "bad things" might prove to be even more divisive and bring odd new forms of self censorship.

Right now it's "Drug usage and violence? Well it's PG-13, so it's probably not too bad."

Without ratings it could easily change to "Drug usage and violence? No way!"
