Ah - I read that one. It's more of a science fiction novel than his usual horror stuff, isn't it? There was a miniseries done a few years back, but I think they changed the story quite a bit. Seems I heard there will be a new one coming soon, though. Why do people think they can improve on Stephen King anyway?
Yes. The Tommyknockers is a bit different from his other books, but he sure can write!! He has the ability to capture and hold your attention.
I don't know why they change things either. Like in the version of The Shining with Jack Nicholson. Yes it was based on a haunted hotel but they left a lot of the book out of it. I saw a 2 part mini series of it with Rebecca De Mornay and that one was truer to the book.
Have you read Under the Dome?? I have and to me the tv series just doesn't cut it. I kinda annoyed my husband and daughter who watched it with me. I kept getting disgusted and was yelling out "THIS WASN'T IN THE BOOK!!!"
I gave my daughter the book to read so she can see the differences as well, but since the book is over 1,000 pages, it may take her awhile.
