Overall I’d have to say that Lost really delivered with this episode, closing the season on a high note that will certainly sustain its buzz going into next February.
I’m especially intrigued by the potential for the flash-forwards. I was genuinely surprised by this, as the flashbacks up until the revealation of Kate were very frustrating and somewhat pointless to the main island story. Once it became clear we were flash-forward, the usual interpretation–the flashback informs actions on the island–was quickly reversed: Events on the island now informed the content of the flash-forward, and the episode quickly locked into revealation. In an instant, we began, for example, to take Ben’s warning seriously, something I never thought we could do given his character’s manipulations throughout this season. It was a true masterstroke of an idea.
But now the cat is out of the bag; you obviously can’t make the switcheroo again, so it will be interesting if they can find other dramatic uses for this device. The downside, obviously, is now we know Jack is miserable after leaving the island, and that is going to hang on every fated move he makes from here on out. That may be a liability for his character, but I have enough faith in the writers to think they’ll work around this. In any event, there wasn’t much point in continuing strictly with the flashbacks; really, how much more backstory was there to be had?
I also now see Desmond and Charlie’s storyline regarding the inevitability of fate as presaging/“laying down the rules” for use of the flash-forward. I thought for most of the season theirs was a neat little story in and of itself, but aside from Charlie’s inevitable sacrifice for the greater good, this subsection of Lost wouldn’t really produce much other than the required death of a major character at season’s end (just to prove that everyone on the show is vulnerable). Now, it seems Fate (with a capital F) is going to play a much bigger role in the series, and having Charlie die the way he did–underscoring the inevitability of Desmond’s predictions–is a way to tell us that what we see in the flash-forwards is 100% real (I reject completely the idea Jack’s future is some alternative reality). If the producers continue with this device into next season, the Desmond/Charlie story was their way of indicating that it’s not going to be part of some elaborate hoax: What we see in the future, much like Desmond’s predictions, we can safely assume will generally come to pass. And, much like Desmond, we may feel a little uncomfortable about knowing too much.
Looking at where we are now–the Others are severely changed/compromised, rescue seems imminent, Locke is becoming scary, and the expectation of more information about post-island life–I am genuinely excited for the possibilities of this series. One could even say the series may no longer just be about the castaways getting off the island; the larger themes of Science vs. Faith and Personal Destiny, planted as background in the earlier seasons, are now coming into the foreground. I think Lost will be a fascinating show to watch in 2008.
