I enjoyed the whole series. It got kind of crazy there toward the end, but I guess Stephen's car accident scrambled his brain a little with the last books. Overall I was happy and pleased. It was an inspiring tale.
I'd suggest reading the first three books and quitting there. And then probably wikipedia who dies by the end just to get some closure. Nothing was missed between the third book and here, except that I hated the series more with every book. Everything I loved in the first book to the second and third, he stripped away and turned into a stupid self analyzing, self worshipping piece of work. Absolutely nothing. It got dumber and dumber, with King writing himself into the series. Really? That's where I lost all care.I couldn't even finish this one. Had to stop halfway, and that'll be the end of that. I usually can't put down a book no matter how bad once I start, but this was a real exception.
I wasn't sure about this series initially, but it didn't take long before I realized that this series would be among my list of the best books of all time.
