Pretty close to the movie

This is one of those rare cases when the movie is better than the book (not because the book is bad or anything, but because the story is easier to understand in film form). Palahniuk's writing style is very fragmented and ADD. Although it's done on purpose, it's still hard to understand what's going on. If I hadn't watched the movie before, I'd probably be confused.

It's not like this book is bad though. A lot of those memorable one-liners in the movie are copied verbatim from the book. And you get a better feel for the narrator's thoughts in the book than in the movie.
