Have you guys ever watched a book to film adaptation that was as good as the source material, or even better? If so, what made the movie better? For me, Fight Club the movie was much better than the book itself. The extended script really breathed some life into Palahniuk's characters, and there was a lot of inner dialogue in the narrarator's POV that was translated into dialogue between him and Tyler Durden. Spoiler And for those who know the famous plot twist of that story, I'm sure you can figure out why it was important to turn that narrative into a dialogue between Cornelius and Tyler instead of keeping it internal. It also maintained its main philosophy about anti-capitalism and the effects of fatherlessness, and is overall just as gritty as the book. The book is good, but the movie is great, and Chuck himself has said that he likes the movie's ending better than the one he originally wrote.
