The book was better than the movie, but you can't beat jack nicholson

Just about ready to wrap up One Flew Over the Cuckoo's Nest by Ken Kesey. I picked it up at the airport on my way to Thailand for something to read on the plane, but since they were showing some pretty good films, I didn't really get into it until I got back. I'm not usually into fiction, but I'm starting to realize how even works of fiction can give a "truthful" representation of reality. I also must admit that unlike non-fiction, fictional works force one to develop a powerful imagination in order to engage with the characters and events. Also, everyone's particular image of these characters and events is unique resulting in as many interpretations as there are people able to read the story. I still find non-fiction more fascinating and enjoy learning about actual or theoretical aspects of the world we live in, but lately I find myself wanting to see more creative ways of presenting that material, such as fictional work.
On that note, being nearly finished with Cuckoo's Nest I ask anyone who knows of some good, intelligent fiction to leave a comment with any recommendations. Thanks!
