As a film critic, you try to keep an open mind;  especially with subject matter that may not be of personal interest in the first place.  Those films have the opportunity to teach something new.  That said, economical documentaries are still my kryptonite – they’re still too dense to comprehend.  Jed Rothstein’s The China Hustle – a film about devious activity on Wall Street – is more proof of that, but it also surprised me.
