“Although it’s hardly the first issue-driven documentary bent on exposing the corrupt practices and outright lies perpetuated by multinational businesses, “Merchants of Doubt” distinguishes itself in part by taking that brand of dishonesty as its very subject. An intelligent, solidly argued and almost too-polished takedown of America’s spin factory — that network of professional fabricators, obfuscators and pseudo-scientists who have lately attempted to muddle the scientific debate around global warming — this is a movie so intrigued by its designated villains that it almost conveys a perverse form of admiration, and the fascination proves contagious. A logical follow-up to his similarly blood-boiling 2009 muckraker “Food, Inc.,” Robert Kenner’s slickly assembled feature may not touch the zeitgeist to the same degree, but should enjoy healthy exposure through Sony Classics following a lively festival run.” – Justin Chang.
