I try not to think too much about conspiracy stuff (real world) but love that aspect of literature, movies, etc. That's not to say that I'm not interested in the real world stuff, I just try not to think about it too much. (You'll go crazy.)
I feel like I know far more about certain 'situations' than the average bear. When I was working on my Bachelor's, back in the early 90's, I did work study for a Rhetoric Professor who was writing a book about the JFK assassination and the media handling of it. I got to fly to TX and walk around Dealy Plaza and the Texas School Book Depository, taking notes and what-not. I've interviewed people claim to have been there and looked at some interviews the Professor did with people who were there and were involved with the newspaper.
It was amazingly interesting. This gets combined with all the books on the subject that I've read, the Warren Commission Report and the report from the House Select Committee on Assassinations, and well, I've definite opinions about what didn't happen.
I'm also a big fan of the X-Files, especially the conspiracy episodes.
I'm looking forward to next month when the movie comes out. I have to say that I'm rather fond of the Lone Gunmen.
I know they were slated to get a spin-off series...did that ever happen? If so, I'll have to track down those episodes.
As for the movie Conspiracy Theory, I thought it's revealed that the Gibson character isn't just a nut, but an asset that's gone underground. The whole thing about him buying that particular book is something he was programmed to do by the CIA (or whichever acronym it was).
