This book is so bizarrely different from the movie it inspired. The things, thus far, that really remain the same are the concept, genre, a handful of characters, and setting. There's also a few things that were kept, though they were changed drastically, including something about Toons and alcohol. I think there's also a line from Eddie Valiant that was kept, too.

Otherwise, entirely different. I'm not super enjoying it? But it's okay. Have no idea how they made such a good movie out of what is, thus far, a mediocre book.
