Movies like this always make me angry at how stupid people can be, IF it were based on a true story and crap like this really happened to this family, the first hour something strange happend I would have been out of that house in no time flat, I don't care how much I had invested in it.
Second I hear no mention of religion but i'm sure these people were, because only people involved in cult activity claim crap like this. Another bogus film to bring your little girl friend to so she can cling to her man and pretend he is protecting her, how sweet.
