I liked the movie Fight Club more than the book. I cannot say the same about the legendary book All Quiet on the Western Front. Comparing the book and the movie makes a huge difference. Recently I wrote an essay about it, check my source to read more information. The harsh realities of war force soldiers to undergo drastic personality transformations making them feel disconnected from their previous way of life. The war separates them from their past both physically and psychologically. Unfortunately, we don't see these subtle moments in the movie.
