A small millennial cult is the ultimate "us versus them" power fantasy. Out of billions of people, god chose you and your fellow believers to avoid his wrath. You get turned into carefree immortals who inherit the Earth (and, with a bit of imagination, the entire cosmos). The people who mocked you, ignored you, oppressed you, and persecuted you have been turned into the dust that you now shake off of your sandals.
And in case you missed it (or simply want to relive those glorious 'last days') there is the "Real Armageddon" blu ray set, so you can enjoy it again and again in brilliantly colored high resolution!
