I totally agree.
The documentary films are definitely the way to introduce these ideas or "theories" to the average person who may not have much exposure to them previously.
I recently found an amazing site that streams a nice collection of Conspiracy Films...I think it's a great assortment that covers a wide range of interesting ideas. Maybe you can help me get the word out about this site:
Conspiracy Revealed - Conspiracy videos, theory and television
The site itself is super nice, but the video player is really extraordinary...you really have to see it to believe it.
Full screen, high quality and no buffering.
check it out.
