NOTE: in case you've not finished off "Lost," I'm going to make the post spoiler-free. But stay away from the meta if you want to avoid spoilers; I'm not going to require that anyone stay away from spoilers.
UPDATE: you can see a few spoilery unanswered Lost questions at my site.
My dear wife and I have been longtime "Lost" fans. We started a year or two in, caught up, stayed hooked.
I grew to respect the writers a lot. Again and again, an apparently random event or character in one episode would be caught up and featured front and center, weeks, months, or even years later. One had the feel of a very deliberate, purposeful venture being unfolded.
So we stayed up (far too) late watching Sunday's grand finale — and came away puzzled and disappointed.
Obviously, many found the ending perfectly clear and delightful. That's great. I guess I must be dim, because I don't see it yet. I was disappointed. We'll probably watch it again, give it another go, see if we can make better sense of it. But for now... the last episode was the first "Lost" episode that ever really let me down.
I've grown accustomed, though, to human writers setting up conundrums they can't solve fully or satisfactorily, so I tempered my expectations... to some degree. Whether Stephen King, C. S. Lewis, J. R. R. Tolkien, Tad Williams, Joss Whedon, Stephen Donaldson, or on and on, I think humans create better dilemmas than they do solutions. In at least some cases, the authors themselves did now know how their stories were going to end when they started them rolling. Sometimes that shows.
But whether carefully planned, or made up on the wing, I can't offhand recall any really ambitious saga whose dénouement left me fully satisfied.
With one exception, of course. That would be actual history itself.
Take prophecy seriously and one sees a very complex weave from start to finish. Take the Bible seriously, and you realize that the Author of both history and prophecy knew the whole from the very start. Human writers may make it up as they go along, but God is the one who declares "the end from the beginning and from ancient times things not yet done, saying, 'My counsel shall stand, and I will accomplish all my purpose'" (Isaiah 46:10).
I am thinking of this now particularly with reference to the "problem" of evil. In history, the villains are monstrous, powerful, dreadful. They fill us with loathing, with horror, with disgust.
Yet we read that God "laughs" at them (Psalm 2:4). Why? Nothing about it looks funny to us, down here on the battlefield.
And I can know it too, to some measure. How? Because I've read the end of the story. And it is completely satisfying, beyond the ability of any human author ever to dream.
