Rather than take down George Bush with smug cheap shots, political scientist Charles Ferguson’s terrific No End in Sight, first released in 2007, simply attacks with the facts. Now, it’s available on YouTube, without interruption and with all its upsetting insights intact. Its methodical, incisive dissection of the Bush administration’s myriad stupidities leading up to the Iraq war make for that rare contemporary documentary that worries less about its entertainment value than building a convincing argument.
