If you really want to start understanding "What is going on" you need to go much further back. I would generally recommend "The Creature at Jekyll Island" by G. Edward Griffin, "The Progressive Era" by Rothbard & Newman, and "The Managerial Revolution" by James Burnham.
Stuff like Zeitgeist and Loose Change were fascinating when I was very young, but I would urge you to watch the Ryan Dawson link I included over any others.
I'm not aware of any 9/11 documentary that has been successfully scrubbed from existence no matter how outside of the mainstream it is.
