LA Weekly review of 'Merchants of Doubt': [Producer Robby] Kenner finds a magnificent antihero in Marc Morano, a cheery, chatty prevaricator who has made a mint by muddying water. His job is to promote skepticism of a truth that even Skeptic magazine believes in, and since Morano's cocksure, and good at yelling on TV, he steamrolls over climate scientists on cable despite his lack of expertise. In interviews, he's disarmingly guileless, happy to brag about all the times he's posted online the email addresses of climate scientists, some of whom turn up to read aloud from the death threats they get. The film and Morano agree on one thing: All that the deniers of climate change have to do to succeed is reduce the country's certainty. They've been wildly successful.'
