Andy Ihnatko, computer columnist and humorist, has a great blog post on the trials of explaining Shallow Hal to his mother. “I was about to sigh the sigh of the ages and patiently re-explain the premise yet again, when I realized that she had, in fact, spotted a logical inconsistency in the film. And I couldn't simply acknowledge that.” So easy to sympathize. (The title’s great too—“Now do Brazil!”).
