HE reader Joe Branham has just pointed out an especially insipid quote from Media By Numbers president Paul Dergarabedian in a just-posted CNN story about the $76.5 million earned this weekend by I Am Legend, which ranks as the largest December opening ever and a “personal best” for star Will Smith. “It’s no wonder Will Smith feels so lonely,” Degarabedian remarked. “Everyone else on earth is in the movie theater.” He sometimes makes me want to scratch the paint off walls with my fingernails, this guy. I’ve been coping with this for years.
