The film has a great villain in climate-change denier and media assassin Marc Morano, who candidly, gleefully admits orchestrating personal attacks on the opposition, encouraging Internet wingnuts to send hate mail to legitimate scientists. “What I enjoy the most is going after individuals,” he says. “We’re the negative force, we’re just trying to stop stuff.” There is a creepy light behind his eyes. He’s in it for the fun.
