Hamlet's post about depressed Avatar fans perhaps able to find happiness in a Second Life Pandora-based sim had a link to this article on CNN Entertainment website. That was rather startling to me. Of course I assume it's overstated, but still, unless it's out-and-out lying some people are sad because they "long to enjoy the beauty of the alien world Pandora."

A couple of things that immediately occured to me:
We already inhabit a world of incredible beauty, and by setting standards very low and based almost entirely on money, have managed to uglify large swathes.
Being depressed because one can't "enjoy the beauty of the alien world Pandora," go to Diagon Alley, fly like Peter Pan, or pilot the Millenium Falcon is something that no one over the maturity level of about age ten will experience.
