The MPAA movie ratings have been a joke for years (as Kirby Dick’s This Film Has Not Yet Been Rated makes abundantly clear) so why should anyone care about their new Red Carpet Ratings alert? Which will include a weekly email blast that will make it easy for parents to get ratings on their work and home computers or handheld devices, blah, blah. Just remember to see Dick’s film, which IFC is opening on 9.1.06.
