Hunter S. Thompson is an odd bird in the American aviary. Admired by the left (the impressive drug intake!), tolerated by the right (the gun fetish!) I can't think of very many other people who get eulogized by "Rolling Stone"'s Jann Werner and Pat Buchanan- but that's more or less what happens in Alex Gibney's "Gonzo: The Life and Work of Doctor Hunter S. Thompson," a documentary narrated by Johnny Depp. Gibney is becoming one of our most prominent documentarians ("Enron: The Smartest Guys in the Room", "Taxi to the Dark Side," an upcoming film on Jack Abramoff), and he's very good at placing a relatively skimpy biography of Thompson within a political context that makes the good doctor seem more like the madcap biological result of the '60s and '70s than a genuine person, (genuine people are boring.) Tom Wolfe and Thompson's great illustrator, Ralph Steadman, also offer their insights. Spider Jerusalem's input must have been left in the cutting room floor.
