It was mostly about a 1630's farming family in America being tortured by some witch in the woods. There was a little too much Jesus praying in the movie for me, but I guess if you're going to have a Satan-goat worshipping witch you need something to counter it with.
It made me appreciate not living in colonial America. It also reminded me of what I think brushwood ladies would love to live out.

I just want to be the goat.
