It's King's self-professed magnum opus. It didn't hit me the way I'd expected or maybe hoped. Overall, I could say I wouldn't have really minded missing the whole thing out. At the same time, there were sections that really got me, specifically the evolution of Jake and Roland's relationship and the death of one of the characters was like a knife. I read the section while walking home from work and after a couple of great wracking sobs burst out of me, I had to put the book away until I got in the house.
The biggest thing for me, though, was that I didn't care how things turned out. Apart from the particularly moving passages, the rest was just a story passing by.
Now, I read with interest the introductions to the books where King says that he received letters from people who were dissatisfied with the way he ended one book and other plot decisions he made. Who are these dickweasels that take it upon themselves to write to an author and tell them they shouldn't have written this or that? Your options as a reader are limited to read or don't. That's it. It's not for you. It's mere coincidence if you like it. Jesus.
