This documentary is absurd, and virtually every one of its central contentions has been refuted. Like others, I would never suggest that something like this should be censored in any way, I do worry, as pohnpei does, that legitimate and well-founded criticism of our government gets conflated with nonsense like this. It is indirectly related to a fear that I have in our information age that we have become too egalitarian in how we assess arguments. The fact that people made a film about 9/11 does not mean that their claims should be weighed the same as the innumerable experts who analyzed the attacks and their aftermath.
I have to agree with pohnpei. I have a hard time with "documentaries" like this. While I am all for criticism and conspiracy theories, some have a place and some do not. I guess I feel as if something as tragic as 911 needs to be handled with more couth.
I don't really think that there is any place for this sort of "documentary." I am not advocating that it should be banned, but I see no value in watching it. When people put forward this sort of crackpot set of ideas, it devalues all valid criticism and skepticism of the government. It allows people who have serious critiques of the government to be lumped in with the sorts of crazies who believe this stuff.
I tend to think that in any open and pluralist social setting, there is a place for wide ranging discussion about historical events or ideas that are commonly shared as factual. Having said this, I do think that there is a place for the 9/11 conspiracy theories that are present. I am not a particular subscriber to them myself, but they have a place. In the name of collecting evidence and point of views from as many sides as possible, I think that the film possesses value in this regard. There should be an openness and transparency in discussion so that even though individuals might disagree with different points of view, there is a shared understanding that the point of view should be able to be accessed and not denied. This might be where the ideas that come out of the film emerge. It is important to be able to allow an exchange of ideas and listen to other points of view. I might disagree or not necessarily accept some of the premises or ideas that come out of the film, but that does not mean that the film loses its right to present its own findings for others to determine their validity. This might be where I think that the value of the film lies.
