How bad is it? It's one of the worst films by goremeister H.G. Lewis.
Should you see it? No.
I went out of my way to find this, as H. G. Lewis' "2000 Maniacs" and "Moonshine Mountain" are both good films dealing with southerners and this one looked to be similar. What we get instead is the last film of veteran actor Tim Holt, playing an Oklahoma fire and brimstone preacher who's killing college girls as revenuers descend on the area looking for moonshiners. One girl gets stoned to death and it's pretty hard to watch. Two others get crucified. The gore isn't enough reason to watch this and there's no other reason to see it.
