A Southerner (Brad Dourif) -- young, poor, ambitious but uneducated -- determines to become something in the world. He decides that the best way to do that is to become a preacher and start up his own church.
This film is brilliant for its examination of religion and for its casting. On the former point, some aspects are clearly exaggerated. The world is full of crazy preachers, but probably not so many in one town that they are stumbling over each other. Is the film against religion? No. On the surface, yes, but it is really against hypocrisy.
And the casting... Harry Dean Stanton and Ned Beatty are great, but Brad Dourif runs the show, and it is a shame his name is not more widely known outside of film fanatic circles...
