Query: Like reading a Dean Koontz novel!

If you like Dean Koontz, you should like this movie. It doesn't spell everything out for you. You have to pay attention, you have to think. You, just like the main character, know something is terribly wrong but what is happening and how? It was really exciting to experience all the terror, mystery and helplessness of Sandra's character right along with her.
