This movie alone convinced two Republicans who I work with that 9-11 was an inside job. One of them is a former Navy Seal and both of them are not dummies and have an above average knowledge of history. I am watching the movie now and am begininng to arrive at some conclusions as to why it will convince more people, faster that 9/11 may well have been an inside job. In several respects it is well made, in some respects not so. I skipped the minutes between 6min and 32 min.
The half hour between minutes 33 and 110 is quite solid.
I think this movie could be a crutial turning point in the mediation of 9/11 history within the United States.
