Someone failed logic class...
So Harvard released a report saying that PG-13 films have gotten progressively vulgar. This isn't too surprising - movie critics such as Roger Ebert and James Berardinelli have been saying it for awhile.

Of course, Thomas Carder thinks that this means CAPalert has won and that American films should be judged by CAP standards NOW!

Choice quotes:

Scanning through the article I find, point by point, the CAP Analysis Model provides and has always provided that which is claimed to be needed but absent from the Motion Picture Association of America (MPAA) rating system: that indeed the CAP Analysis Model could replace the MPAA. And the CAP Analysis Model provides it OBJECTIVELY, not vulnerable to mood and preference subjectivity so YOU can be in a better position to have the information YOU need to make an informed moral decision whether a film is fit for your kids (or yourself).

Yeah, because basing a rating system on the Christian bible is totally "objective."
