Perhaps only for aficionados of the left-right debates, and perhaps only for those who are drawn to American politics, but this may well represent just what it says it is, "The Ultimate Fight between Left and Right".
In the red corner, we have Bill Ayres, the former leader of the Weathermen in the 1960s, an American domestic terrorist and the actual writer of Barack Obama's Dreams from my Father.
In the blue corner, Dinesh D'Souza, a great defender of American values and ideals. He produced the documentary, in the middle of the 2012 election and is now by the highly politicised American justice system for violating US election law, possibly the only person in the US charged with this crime following the last election.
Two hours long.
