I haven't. But based on a recent radio interview with the film maker that I caught a part of, I suspect its weak. The guy went on and on about Obama but didn't mention once that he/Obama was a Marxist. Maybe I came in too late and missed that part?
I’m not familiar with D’Souza’s entire premise, but from what I understand Obama was/is influenced by his phantom father’s hate of colonialism and is motivated by that and is pursuing that dream of his father. I’m sure it’s more complicated than what I’m describing. I believe that Obama was much more influenced by the radicals that were actually around him including his grandparents and mother.
I did find this about the movie:
The documentary, based on Dinesh D‘Souza’s book “The Roots of Obama’s Rage,” features an interview with President Obama’s impoverished half-brother, George Obama, and sheds light on the president’s relationship with his avowed communist mentor Frank Marshall Davis.
