I never saw the movie but liked the book. All about the aftermath of the fire bombing of Dresden. And focussed a lot on an insane optometrist. Seems like it would be difficult to translate to a movie. I have read a few Vonnegut books over the last year and it’s cool the way his characters (like Kilgore Trout) overlap from book to book.
Naked Lunch was another one that the movie was nothing like the book. Although, I only made it about half way through the book and it got a little too weird even for me.
