"Voyeur," a documentary purportedly about an infamous voyeur, should really be titled "Pseudo-Journalist," since what it really demonstrates is what a terrible writer Gay Talese is. It's not "true crime," since so many of the claims in it are debatable or demonstrably false.
Talese correctly notes that it's dangerous to rely on just once source, but never bothers to check on important alleged facts of this story himself. He seems unfamiliar with Google, only learning from his daughter and others about details readily available online. He never checks property records central to the story and does a sloppy job checking on a crime mentioned by the voyeur, Gerald Foos. He unconvincingly brushes aside key discrepancies on dates.
At one point, when Foos claims that his Mickey Mantle baseball card is worth a huge sum, Talese laments, "How am I supposed to know if he is lying?" How about looking it up online? Or asking someone knowledgable? His methods are so shoddy, one has to wonder about the rest of his books.
At another point, explaining why he participated in group sex as part of his research for a book on sex in America, Talese explains that, as a reporter you can't just observe, you have to experience. Really? Did he have to kill anyone as part of his reporting on the mob? Can no one write about war, space exploration, professional sports, medical research, or anything else without being an active participant?
The documentary begins with him talking about his townhouse in Manhattan and his impeccably tailored suits. He should have spent some of his apparent wealth hiring a research assistant to ensure that what he wrote wasn't garbage. "Voyeur" reveals him wearing the emperor's clothes.
