I'll always remember the end credits sequence, which is a series of stills from a flashback to the title characters child-hood days as a snake-handler, the congregation with their arms upraised while some kind of backwoods-y country hymn is sung.
Is it telekinesis? The summary makes it sounds like she just controls snakes.
I'm picturing snakes crawling inside the car engines and causing them to explode, like that killer ant movie where ants formed a living chain to short out a vehicle. You know, that killer ant movie with the two naked scientists at the end where no one here can ever remember the name of.
