It's on Frontline tonight:

A couple of things from this preview: “Zero Dark Thirty” was never “bound to be a blockbuster” nor was it supposed to be; it was a small, prestige picture. And all critics didn't rave; there was sharp controversy back then. My own review of “Zero Dark Thirty” is full of mixed feelings and failed attempts to parse it all out. 

Anyway, I plan to check this out.
