Compare that nonsense with the evil thing (I forget the character name) in
Needful Things. It is seemingly a nice old gentleman who sells stuff. Slowly, his evil character develops by showing itself as a master of deceit, rancor, and strife. It is a subtle, puppet-master character. He delegates violence; he doesn’t exercise it. He acts like a real-life devil.
Consider the scene in which the woman (again, I don’t recall any names) goes down on her knees to give him fellatio in exchange for something she wants and needs (arthritis panacea, if I remember correctly). As she unbuttons his zipper, he looks down at her with contempt and repugnance and then he pushes her away. He’s had his fun; he sucked her pain, humiliation, and weakness, and he is satisfied. A psychological fellatio took the place of an actual one. This is powerful yet subtle writing.
In addition,
Needful Things doesn’t have the standard good-versus-evil dichotomy. The people of the town are at once the thing’s victims and its accomplices. As such, they pose a problem to the reader.
