Time Out says
Gibney, who previously showed his hunger for getting to grips with the underbelly of the American political and corporate condition in ‘Taxi to the Dark Side’ and ‘Enron: the Smartest Guys in the Room’ brings this lighter subject to vivid life with reconstructions and ample use of clips and photos. Most illuminating are the episodes either side of Thompson’s overworn ‘Fear and Loathing in Las Vegas’ shenanigans in 1971 (for which Gibney draws heavily on Terry Gilliam’s film). He takes a broader view of the man to confirm his credentials as a fearless investigative writer when researching his 1966 book on the Hell’s Angels and to ponder his later inability to compose anything decent at all (a depressing bit of footage has him drunkenly playing ‘Candle in the Wind’ in a hotel room while failing to engage with a typewriter). Gibney is good on the Nixon era (Pat Buchanan, George McGovern and Jimmy Carter pitch in) but the film’s plea that we need Thompson now more than ever is a little misty-eyed: Thompson’s day was long gone by the time he put a gun to his head.
