Roger Ebert is taking issue with the MPAA again over their PG-13 rating for the movie Whale Rider. While I haven't seen the movie, I nevertheless agree with him. I'd make an argument for his case, but I'd only be repeating what he has already done a good job of explaining. The MPAA's rating system has become all but useless. Ratings do not match the movies they are paired with and theaters and parents make little effort to enforce the system anyway.
