This is the first time I've read Slaughterhouse-Five or Kurt Vonnegut. The novel is difficult to categorize. It may be science-fiction, or you might call it magical realism. It also has portions of historical fiction. It is decidedly satirical. It is set...well it is similarly difficult to describe the setting as it involves time travel and inter-galactic travel. A large portion of the story is set in World War II, Germany, Dresden to be precise. It is semi-autobiographical as Vonnegut was a P.O.W. and present during the bombing of Dresden.
I have mixed emotions. This was certainly easy to read and Vonnegut has a certain aloof sense of humor that I find amusing. Mostly, I think Vonnegut has ADD, just as the main figure Billy Pilgrim.
To be more precise, and to quote: Billy Pilgrim has come unstuck in time.
Film Rendition: 1972 version starring Michael Sacks as Billy, and a bunch of other actors you haven't heard of. It was a decent portrayal of a story that would be hard to tell in film. Read the book, skip the movie.
