Chipperish Media/How Story Works chief Lani Diane Rich sat down with me to see which Son Of Sam stories worked -- Investigation Discovery's, Smithsonian's, or the 1985 CBS version starring Martin Sheen -- and the one that's so bad it's good may surprise you. Why do David Berkowitz's crimes still preoccupy us? What's with every single Sam-doc producer having to put several minutes of public-domain disco on the soundtrack? And who decided Eriq LaSalle should only have one line? We'll try to answer all these questions in our latest episode.
