“Where in the World Is Osama Bin Laden?” doesn’t really know what it wants to be. It’s a comedy, a political essay, a rumination on incipient fatherhood (yes, we get to see Spurlock’s baby being born) and a naif’s-eye survey of current events. The film could have served as a primer on the past 50 years of U.S.-Mideast history and post-9/11 developments if its flippancy didn’t disqualify it as such. People used to get upset about Jesse Jackson or Jimmy Carter operating in the sphere of foreign policy; imagine what they’ll think of Morgan Spurlock, who, if he’s so worried about America’s image being tarnished abroad, might consider staying home.
