But if you want to read good Gaiman, please for the love of god don't read his novelizatoon of Neverwhere. If kb found Shadows lack of autonomy annoying he will only be more irritated by the "protagonist"/main character of Neverwhere.
Most of the point of view characters in Sandman were the same way. He does it a lot. It makes less sense in Neverwhere though, because Door isn't any more alien than most fantasy protagonists. He didn't really need to add someone for you to relate to.
This is very true - I mentioned it because most of his other "cinematic" works like Coraline are aimed at children. I just looked into other novels by him to recommend something, and struck out. Good Omens was a lot of fun, but rather different than his other work. I had no idea how little he'd actually written for adult novels!
