Yeah, sorry, I guess I should present more facts, but I'm certainly not basing what I think on the movie alone.
And I certainly don't believe everything that is said. There is quite a bit I disagree with in the movie because
it seems to extrapolate a lot of information. I could probably put references here, but you're better off finding
the facts yourself (while being critical of the sources).
Since you mentioned it, there's whole groups of Architects and Engineers that don't buy the official explanation:
Architects & Engineers for 9/11 Truth Notice how in the top right of the site, they emphasize
"9/11: Re-examining the destruction of the 3 WTC skyscrapers"They emphasize the three because most engineers and architects agree that the explanation for the twin towers is possible (regardless of probability), but WTC7 makes less sense. The twin towers are believable because of the plane impacts and how the jet fuel just happened to burn in a structurally critical part of the buildings, weakening them. But WTC7 was not hit by a plane, so it's main structures should have been intact. The official reports say that it was damaged much worse, and even if that is true, the building was not full of jet fuel to reach temperatures like that of the twin towers, let alone result in the type of collapse pattern observed...
Well, anyways this is starting to become too much work to look into... and I'm starting to not care anymore... but if you want to focus on the outcomes of all this, the movie has a lot to say about that too. Actually that's the purpose of it all: it tries to explore where all of this has taken us-- and where it could take us. For instance, scared people turn to the government, which in turn could take advantage of that trust and pass laws that take away civil liberties by implanting microchips in your brains, thus controlling the population

okay I didn't believe that one, but could that happen? Will that happen? Who knows.
Anyways, I'm not really trying to draw any conclusions here or start an argument, but just suggest that there may be more behind what we perceive than what we think, and it's not such a bad idea to be aware of the possibilities.
