I'm revising my previous estimation of this book up one star. 
 I'm gonna be a little spoilery. :) 
 Why? The re-read was actually rather satisfying. Yes, it's a novel about survival and all the kinds of crap that men make women do to satisfy themselves, but it's also a rather moving novel about keeping (or losing) one's sanity in the face of all those expectations. 
 Never mind the sheer horror of being handcuffed to a bed without hope of being saved because your lover just keeled over, or watching a dog eat your husband as you go thirsty. It's a lot more than just that. It's memories and other humiliations and the struggle to find oneself through one hell of an ordeal. 
 Plus, I kinda like the fact that we're dealing with a very Poe-ish or Aristotelian art-ethic here. It's very focused in time and place, forcing us to go down deep into the subconscious. I can't help but appreciate that more now than when I was younger. *shrug* 
 Either way, I also enjoyed the almost tacked-on feel of the extended denouement. It really gave a sense of reflection and of shoring up her defenses after having them all stripped away, both literally and figuratively. I felt the power of the positive reversal. 
 Now, I should say that I'm revising this from my three stars to four based mainly on the fact that the novel is good on its own, but when I chose to give it three (from memory), I did so based on my enjoyment in comparison with the rest of Stephen King's works. It isn't his strongest novel by far, but it was still quite enjoyable. 
 I think I'm going to really enjoy the movie in a few days. :)
