Reliably liberal New York Times movie critic Manohla Dargis lauded activist-actor Leonardo DiCaprio's "The 11th Hour," the latest documentary of environmental apocalypse.

"To judge from all the gas-guzzlers still fouling the air and the plastic bottles clogging the dumps, it appears that the news that we are killing ourselves and the world with our greed and garbage hasn't sunk in. That's one reason 'The 11th Hour,' an unnerving, surprisingly affecting documentary about our environmental calamity, is such essential viewing. It may not change your life, but it may inspire you to recycle that old slogan-button your folks pinned on their dashikis back in the day: If you're not part of the solution, you're part of the problem."
