Less cinematically attractive and intimate than An Inconvenient Truth, The 11th Hour still manages to be worthy, if verbose companion piece on the sad, looming state of Earth.
Eco-activism is provided by the likes of Leonardo DiCaprio, a co-producer, co-writer, and narrator. His celebrity clout, along with sister directors Leila Conners Peterson and Nadia Conners, offers insight into the dire trend of climate change.
Whether tsunamis, hurricanes, rush-hour traffic, deforestation, fishing, or a slaughterhouse, the images, quickly edited, is part of the presentation showing how future generations may be hard-pressed to enjoy life in the same way their predecessors did.
Global warming has resulted from increased reliance on fossils and overuse of limited resources. When DiCaprio isn't reciting the doleful data, there is an abundance of loquacious, informative talking heads. They include, Mikhail Gorbachev, Lester Brown, Andy Revkin, and Stephen Hawking. Their philosophizing ideas put emphasis on where the humanistic fits in with all other life.
The 11th Hour even has designs on addressing the problem, especially in urban areas. The architecture would be ecologically-structured, along with renewable energy sources to nurture the cityscape.
One notices that the sibling directors had a solid production crew to make the sights and sounds absorbing, even if the former is too viscous. What should accompany this green reflection on phenomena and integration is more educational opportunities for those who don't have to live in such a potentially woeful state.
