Query: And I base this on absolutely nothing......

A film which goes on and on and on about Obama's father. The film tells nothing about Obama except "what do we really know" (apart from his entire life history which was spent in the US). The film also fails to show any connection between the beliefs of Obama's estranged father and Obama himself, yet clearly states that Obama is highly influenced by these beliefs - based on absolutely nothing. Classic bait and switch - no new evidence or facts.
