atheist tone?

I don't know if it was intentionally written as such, but the entire movie struck me as a parable showing the flaws of various types of religions faith. The homeless leader as early catholic priest who won't let anyone read the holy material to guard his own status, the light that's supposed to be a godlike force but is really a bulb in a somewhat analogous form to the transubstantiation, his assurances to everyone that there's a paradise and a king that will only talk to him, and finally the splinter follower who maintained the faith in the message but not the messenger. I suspect it's also one of the reasons a lot of people found it disquieting, there wasn't too heavy a difference in the way the homeless man led his followers and the way that almost all religions operate. He just chose a message a little easier to falsify.
