What's the one book that absolutely must be a TV show, NOT a movie?

The other day, we heard that Y: The Last Man is still going to be a movie. But meanwhile, Under the Dome is a hit TV show and Outlander is coming to Starz. What are the qualities that make a book (or comic) better suited to television than movies? And what's the one book that deserves a long-running TV series instead of a movie?

Please include a picture of your chosen book or graphic novel — and for bonus points, explain why you think certain books should be on television instead of the movies. Thanks!
