In his review of An Inconvenient Truth, Financial Times film correspondent Nigel Andrews says:

If I were an opinionated madman licensed to be oracular – and I ignore retorts of “why say ‘if’?” – I would aver this: the greatest disaster in the western world in the 21st century to date has been the victory of George W. Bush over Al Gore. Greater than 9/11? Yes, because it incorporated 9/11. It engendered it. Would terrorists have struck a Gore-led US? Since al-Qaeda’s stated aim was to avenge the desecration of Saudi Arabian soil by foreign troops in the first Gulf war, wasn’t Bush paying for Bush, the son for the father?

Most of Andrews’ other comments are just as accurate; he alleges that the USA did not sign Kyoto (President Clinton did) and that the film is worth 4 stars. He does, however, discern that the movie is a good campaign ad. I suspect he’s right there.
