"Waiting for Armageddon" is a 2009 documentary about Evangelical Christians and their beliefs about the Rapture, the Tribulation and the whole End Times mythology.
These people are bat shit crazy. If they would just go off in a corner with their fairy tales, no one would care. Unfortunately they tend to be socially and politically active which makes them dangerous.
They are so dangerous that I think they are far and away the greatest danger to the security of Western Democracy. They envision a "victory" scenario which is far worse than any "defeat" that I can imagine.
