If you are at all interested in horror movies and books from 1950 to 1980, if you are interested in the mythic underpinnings of the horror genre, or if you just enjoy good, rational and reasonable analysis, this is the book for you. King's literary "voice" is, as always, easy to relate to and even easier to understand. The book does not, however, rely entirely on King's own analysis, as he includes the writings of others and even from the authors in many cases. I've read dozens of books about the horror genre, but this is the one that first got me interested in what made it all work in the first place.
