An Inconvenient Truth, 2006

From director Davis Guggenheim comes the Sundance Film Festival hit, An Inconvenient Truth, which offers a passionate and inspirational look at one man's fervent crusade to halt global warming's deadly progress in its tracks by exposing the myths and misconceptions that surround it. A catastrophe we have helped create. Humanity is sitting on a ticking time bomb!

Davis Guggenheim's documentary is based mostly on Gore's multimedia presentation on climate change, a lecture he has delivered hundreds of times in recent months. While Gore is managing the show with powerful efficiency, there is nothing dry or tired about it. The former Vice President Al Gore re-set the course of his life to focus on a last-ditch, all-out effort to help save the planet from irrevocable change. With wit, intelligence and hope, An Inconvenient Truth ultimately brings home Gore's persuasive argument that we can no longer afford to view global warming as a political issue - rather, it is the biggest moral challenge facing our global civilization.

I did not find a single negative review based solely on the film’s art. But I found so many errors in this movie!
If the movie will help you judge for yourself which direction we should take, then Gore should dig deeper into the material. If you want to read a full report, you can download this pdf file.
However, this is on the whole a good film. It explains the facts very well, explains away the objections that people have been hearing about from the media and is also pretty funny at times.
