My problem with the finale is that, although it was a moving, fitting tribute to all the characters we've come to love (and hate) over the last six years, it answered *nothing* about the island. It answered plenty about the flash-sideways reality of this past season, but almost nothing about the five years before it. If you ask me, it was a huge slap in the face of some of the fans. It's Faith vs. Science all over again... and what we got hit with last night was a big dose of faith, and very little science. Five years of electro-magnetic pockets, time-traveling rabbits and people, name-changing scientists, whispering in the jungle, pneumatic tubes dumping observational journals into the middle of nowhere, and we get no more than the equivalent of the deep philosophical meaning thought up by the two plumbers who wrote the Matrix.

Worst of all, there are long-time followers of the show that are confused by the ending. Have they been dead all along? Did Hurley create the sideways reality now? I guess the dog distracted them during a key conversation.
The main questions I wanted answered, such as where the island came from, why do ghosts sometimes get stuck there, why does it heal people, who originally built the temple and the statue, and what the heck was that huge bird that called Hurley's name all about... why, those things are apparently unimportant. No, clearly what's important is that our castaways created such a deep, lasting bond that they can't go anywhere unless they go together. Just like teenaged girls at the mall.
The show IS a journey, and one that I think is worth taking... just so long as you can easily "Let Go" of all your questions at the very end.
