The success of The Ring and many related motion pictures surrounding it are easy to demonstrate. However, it is substantially harder for fans of the genre to navigate their way through the confusing tangle of movies flooding video shop shelves or local multiplexes. There are 10 Ring movies in different formats from 3 different countries, 7 versions of The Grudge all with essentially the same title and all by the same creator - 2 competing versions of which were released simultaneously in American theatres. Where do you start? With this book.
