Today, I found this article by J.J. Abrams on wired.com.
Being a tremendous fan of Lost, I was interested to see what he'd say about "the magic of mystery", and although I've already heard a lot of the points he makes before, he hits a few nails on the head. There is joy in the act of finding out for yourself, no matter what media you choose. For me, it's books, and going along for the ride each author has constructed. Or enjoying my episodes of Lost, even if I don't really know (or care) what's behind the curtain of this series, so to speak.
The story Abrams relates about his Super Mario days, particularly the final line, is worth the price of admission though.
