"Clearly, smoking is increasingly an unacceptable behavior in our society. . . . No parent wants their child to take up the habit. The appropriate response of the rating system is to give more information to parents on this issue."
If that's really their approach then they should also include phrase such as "glamourized drinking", "pervasive drug use" and "frequent use of guns" in their ratings. I'm pretty sure at least as many parents would have similar feelings about those issues...
I don't have a problem with the idea of the MPAA supplying information, but it seems to be very inconsistent about what it chooses to consider as noteworthy.
