I do not re-read books. The story is what I am really after, so "reading" is more a means to an end. I also have a voracious appetite for new things.
Though I am tempted to re-read certain stories, such as Hitchhiker's Guide to the Galaxy or some short stories I have read.
However, movies and TV shows I will rewatch a lot (because the experience is a big part of it), and don't get me started on PC games.
