I consider the review to be incomplete and stilted. Of course, since I haven't read other reviews by Hoberman, the format may be his chosen shtick for reviews.

What it did was motivate me to obtain a bit of background info on the writer of this story.

After a bit of research, it's safe to state that to label D'Souza as a right wing conservative is akin to describing hundred plus degree weather as being a bit warm.

No matter whether conceived by touted liberals or conservatives, I abhor these types of productions where the aim is solely to serve as a tool to deliver a distorted and derisive piece of fiction as a probable truth scenario to install rabid fear and distrust. 

Thankfully Wiki included this too:

The film has been widely critiqued on the grounds that what D'Souza posits as being an investigation into Obama includes considerable projection and speculation and selective borrowing from Obama's own autobiography in seeking to prove D'Souza's psychoanalysis of Obama.[

He has attributed many modern social problems to what he calls the "cultural left". In his recent book The Enemy at Home: The Cultural Left and Its Responsibility for 9/11, he wrote that:
