The plot is bad, and though billed as a horror/suspense movie, it's neither. The acting was sub par but not the worst, with one exception; the wife. I thought she was decent in Westworld, but here she is hollow, lacks sincerity and is simply not a believable character. Who would want to be with her? The dialogue as most people have mentioned is so bad that it's borderline comedy. There weren't even any decent shots of the bayou. Avoid it.
