Query: One of the worst B movives I've ever seen

- The acting is so fake it's boring.- There is no emotion or suspense. For example, in the scene where Paul and Karla drugged and raped Karla's sister to death, the actors displayed no emotion. It's so insipid that I felt nothingIn short, it's one of the worst B movies I've ever seen. It's better to read the book on this crime.
