Great film, but I found the ending too over the top
It would have been much better if it ended right after Elmer gave his speech to Sharon about wanting to live a normal life and take their children to ballgames. Sharon would then see the shooting star, think God put the two of them together to do revivals, and go back into the Tabernacle expecting Elmer to follow her only to find that he's left.
Instead we got the weird faith healing scene (which hadn't been done to such an extent in the rest of the film), then the over the top fire with Sharon throwing away all caution and burning to death. And a sing-a-long after the fire to make things worse.
