First of all, Pet Semetary is AWESOME and I'm suprised there isn't more discussion about it.
Couple of things I want to mention:
Page 220 (yeah, I recorded it incase I ever wanted to read over it again), there is mention made of Ellie's friend Marie. This was after Church had come back from the dead and it is mentiond that whenever Marie and Ellie hang out, Rachel always gets the impulse to check Ellie's hair for nits. It is also mentioned that Marie always looks malnourished, and has such a thin face, deathly looking was the impression that I got from the description. That section seemed subtly forced in to me, and all throughout the rest of the book I was waiting for mention that Marie was another attempt at a ressurection. It just seemed like King was planting the seed for Louis to find out that Marie was a ressurected. Alas, it was never brought up again and I guess it was just me reading way too far into it.
And a question to you: What do you think happened to Louis? The movie, from what I've read, seemed to take it to mean that Rachel was another broken ressurected, and that's probably true, but as I read the last few pages, I spun myself an elaborate, yet semi-plausable near-conspiracy theory. I have no doubt that there are other people who thought this too.
What if Louis and the ressurected Rachel had become the new Jud and Norma? What if Jud and Norma had gone through the exact same process years earlier? They'd had a kid, the kid had gotten killed, Jud tries to ressurect the kid, kid kills Norma, Jud kills kid, Jud ages considerably by the shock (this would explain his apparant activeness despite his very old age) and ressurects Norma who, due to the speediness of her ressurection, was able to retain a large part of her humanity, but her crippling athiritis (sp?) was a side effect of this. I always found it strange that we hardly ever saw Norma, and so hardly got a taste of what she was really like. So what if Louis and Rachel became 'the next generation' of this?
I realise that the above is quite impossibleand there are probably many reasons why it doesn't work, but by god if it isn't fun to think up these ideas and think beyond the page, right?
So yeah, what are your opinions on the ending?
