MANHUNT: The Search for Bin Laden is an HBO documentary covering (basically) the same story that ZERO DARK THIRTY did, except in this case it is a well made and believable film. ZERO DARK THIRTY was a terrible film (you can read my review here), but MANHUNT is quite good. It's nice to hear the story of the women CIA analysts directly from them rather than a fictional and completely unrealistic hollywood portrayal. These women are real heroes, and they had to put up with a lot of crap from their male counterparts at the CIA.
MANHUNT is not without flaws. It's a bit long, and the opening half hour or so would probably be very confusing if I did not already know much of the story from other sources. But it is definitely worth viewing, and a good addition to the documentaries about 9/11 and its aftermath.
