The movie is about the financial crisis, and Moore is not mincing words. Describing the project in this Reuters story, he says that he made the movie to find out why "the wealthy" "systematically set about to fleece the American people out of their hard-earned money." Well then -- it's good to know he went into the filmmaking process with an open mind.
I don't have a problem with overtly political documentaries, though my personal fondness for capitalism will probably make this movie a tough sit for me. I do think, though, that Moore is most interesting when he is more curious than polemical: it's no coincidence that his best film is the ambivalent, conflicted Bowling for Columbine. Given the amount of news coverage the subject has gotten, and given that we know pretty much precisely what Moore will say, I'm just not sure how much use there is for an angry, breezily edited two-hour look at the financial crisis.
But: populism rarely fails. As with Moore's last few films, look for Untitled Recession Documentary to be the rare doc to receive a semblance of a wide release this fall.
