I'm not the only one to have had this idea of reading the complete Stephen King and heartily recommend you check out Laura's blog - http://devouringtexts.blogspot.com
Not only does she write much longer and more interesting posts on the books, she also offers a much more critical review.
The thing that really blows me away about this blog is that not only does it not take Laura a month plus to read each book, she's reading and watching much more besides and writing similarly involved posts for all of them.
For her Stephen King posts, go to http://devouringtexts.blogspot.com/p/challenges.html and scroll down a bit. While you're there, get stuck into check the rest of the blog. It is awesome.
