I suppose I can't blame the reader for wanting to wanting to escape the world of today. There is little happening that brings us any pleasure, and the media beats the bad news into us until, by the end of the day we feel like a piece of swiss steak that has been hammered full of bile. As Wordsworth lamented, "The world is too much with us; late and soon...".
On a positive note, because of the YA craze, more of today's young adults are now reading, rather than watching inane television programs and playing video games. I don't have the desire or the ability to write in this genre, but I say, "More power to those of you who do." The world will be better for your presence.
