So the reverend was tired of serving a Swedish church of losers?
He could have migrated to USA and started a "megachurch" and made lots of money by fooling people's minds. He would have been rich this idiot!
share"Megachurches" and televangelists catapulted into vast wealth are the creatures of a culture west of the pond, and of a later era than when WINTER LIGHT was made.
But beyond those facts, you seem to have missed the point of this movie, which is "pointlessness" itself. Not that I fully agree with it, myself, but disillusionment and crises of faith are human problems to be found everywhere, all the time, from the BEGINNING of time.
