Just watched it. I have to say, I'm really disappointed. Especially after seeing King and the Writer/Director gloat about how they put the script with a lower budget studio than their offers, just to keep the ending that no studio wanted to shoot.
Steve is notorious for having no idea how to end his books. Just look at The Dark Tower series. Great series, horrible ending. He could have stopped anywhere along the way and would have had a truly epic series, especially had he cut out the whole Metafiction whining about getting hit by a car scenes.
For those of you who haven't read the Dark Tower Series, he literally brings the entire plot to a grinding halt around book 7 or 8, pulls you back into normal, everyday life, out of this epic fantasy series, just so he can get in some good jabs at the guy who ran into him with a car while he was writing the book. And it's all downhill from there.
Steven King, whatever you think about his books or his writing, is a talented storyteller. It's really unfortunate that he's accepting outside input on how to end his own scripts instead of just going with what happened in the book.
