It

This was way too long, definitely great in parts, but wayyyyyyyyy too long.

After reading and loving Misery and The Shining I have now decided that King is brilliant with smaller self contained narratives - I won't be doing any further research to confirm this.

Also, it was kind of distracting that he made the “horror fiction author” character the cool smart hyper-capable brave leader who sleeps with all the beautiful women and every other character idolises.

I gotta say, I personally loved the ending for its sheer insanity. I haven't seen the movies but I strongly suspect they've changed one specific scene.
