Mark Shea on Lost.

"Rediscovering mystery in a post-Christian culture":

If there is any single word that really sums up the atmosphere of “Lost,” it is mystery. Creator J.J. Abrams remarks that when he was a boy, he sent away for a box from some magic trick supplier, and when he received it, he found that it had a huge question mark on the side. He never opened it, and he still has it: a reminder each day of the fact that it’s what you don’t know and can’t quite see or understand that is such a potent force in stories, as in life. “Lost” reflects this.

Part of the fascination of the show is the way in which it is structured, which emphasizes this element of mystery.

This really picks up on what I find fascinating about the show. I'd never thought to call it "mystery" but that is really what it's all about. Really, mystery is what makes everything meaningful to us. When we find some that we'd like to get to know, it's the mystery of the other that drives us to be open with them. It's the same thing with the world around us - I think about walking through the woods, anticipating what could be up ahead.

And it's the same thing with God, whose depths are endless. Then the mystery will never end and we can just keep going deeper.
