There are definitions (I quoted one above) that say a documentary is supposed to be objective.  The reality is there isn't unique words to describe one that is and one that isn't, so both instances pass as documentary.

The point here is that F911 is not objective.  So this notion of 59 deceits of F911 is itself deceitful.  Most of these deceits (and other critics as well) consist of claims that certain facts were left out or taken out of context.  Well no shit!  It's not supposed to be objective.  We take away much of their ammo away if make clear that the film is not supposed to be objective.
