As a writer, I find it difficult to articulate gut reactions without enough time to let my thoughts cook a bit. Hence, my belated notes on the end of Lost.
I'm not a mega-fan, who sifts and speculates on every mystery. The only way I could watch the final season unfold was to suspend questions and accept the enigmatic, sometimes ridiculously twisted, story presented to us. So, I won't speculate here. Lost ended well. It was by no means a perfectly-written or clearly rendered story, but I am impressed by its capacity for making viewers think... especially in an age where entertainment is for the most part easy and mindless. In watching this show, I had no idea what to expect from week to week, no idea what all the pieces were leading to. And, of course, there are far too many to recount here.
And even better, the writers of Lost do not answer all of the questions. They answer what is important by focusing on the characters in the richness of a flashback/flashforward/flashsideways story. Flash sideways in particular and the links between one's real life and the afterlife, those connections between characters that we thought were once lost but definitely are not (i.e. Claire and Charley, Sawyer and Juliette). And... death is not the end of all that we know; it isn't lonely; it isn't sad. It's the peaceful beginning of something new.
For these and many other things in the crazy saga that was Lost, I am completely satisfied. The mysteries live on. They will keep fans and viewers thinking for decades to come. Bravo!
