Cujo is a hard book to read. It's a short book, but there are certain scenes that just gut me. And all those sections occur in the last 25 pages of the book. The first half of this book goes by rather quickly. Then Donna and Tad get stuck out at Camber's place and I simply do not want to continue reading. The first time I read this book was after having watched the movie. Cool enough flick. Slasher film with a dog instead of a masked killer. Survivor is the woman and her son. Rock on. I don't like that the dog was used as a monster, but I dealt with it because poor Cuje was sick. And then I read the book.
There is a big fucking tie-in between Cujo and the rest of King's books that no one ever mentions. My theory is, as far as I know, not impossible. Firstly, Cujo's behavior in the book is constantly referred to as odd. This is aside from the fact that he has rabies. Many times, characters in the book refer to Cujo as more than just a sick dog. Secondly, the closet. Something's living in Tad's closet. This is made cement at the end of the book when Tad's father Vic watches the door knob turn and the door open all by its lonesome. Finally, Frank Dodd is called the monster of Castle Rock at the beginning of the book, and then King goes on to say that that monster returns in 1980. A monster. A monster that can take different forms. A monster that is active in Castle Rock during the time Pennywise is supposedly asleep in Derry. A monster that changes shapes. See where I'm going with this? Think of the gigantic bird that ravages the dance (at least I think it was a dance) in It. Now, stay with me, think about the fact that King wrote The Dead Zone, Cujo, and Pet Sematary all while writing It. Also there are mentions of this "monster" in both Insomnia and the Dark Tower series. Conspiracy theory established. Debunk in the comment section below.
