A Poll: What Makes For a Memorable Book and/or Movie?

I have an inquiring mind and would like to know: Have you ever read a book or watched a movie that you just can't get out of your head?

Every writer's dream is to pen a story that will linger in the reader's mind until he/she expires. But, what makes a story or movie memorable? That is the BIG question. Give us your opinion.

Will you share that memorable book and/or movie title with readers and tell us why you think it (or they) should make it...or "did make" it to the top?

Please post a comment. This should prove interesting.
