I've been in love with the show LOST ever since I got to the fourth episode and saw John Locke walking around. That sealed it - I was in for the long haul and would watch this show until the end.

I have not often been this disappointed.
Bear in mind, I'm a pretty easygoing fan. I don't mind if things are not perfect, and I don't need every little thing answered. But I do need the show to make some sense - and LOST doesn't. We have been watching for six years hoping to understand the fascinating mysteries we've been shown. How do phantasms appear on (and off) The Island? How are people's lives controlled by The Island no matter where they are in the world? Certain characters show special abilities or interesting back stories only to be shoved off of the series and replaced with new mysteries that would also leave us wondering. Like I said, I'm not one of those fans who wants to know where each character was born and why the stage lighting was off in a certain scene - I just want to understand the mysteries that were featured on the show. Imagine if Sherlock Holmes wandered off from Moriarty's trail and never went back - it wouldn't be unreasonable to wonder what became of the arch-villain.
We have our theories. In the absence of actual reveals fans are providing theories to answer these big questions, but the theories are all different because the show simply didn't bother to answer the questions it raised or even give us enough hints so we could draw our own conclusions. Instead, the finale was just a pulpit for the personal philosophical views of the producers. They couldn't be bothered to tell the story, because they had an agenda to pursue.

The real purpose of this show has become a religious one. As the show was wrapping up and giving us its dramatic ending, the main character was wandering around in a church rectory in front of a stained glass window that contained symbols from many religions (like those "coexist" bumper stickers). As a discussion of life, death, and ascension (or, "moving on") took place I realized that I had been waiting all this time for the producers to promote their Universalist religion; like a kid who has been dragged to church, I rolled my eyes and waited for the sermon to end. (It's pretty bad when a Southern Baptist like me accuses you of being preachy. I've never thought pop-culture should be used to ambush those you with to proselytize.)

This concept of spiritually "moving on" through our life's work is not a new development for LOST. In the season five finale, the mysterious entity Jacob is reading Flannery O'Connor's
All That Rises Must Converge. This references an
old theory about human consciousness and ascension, but is also a statement that rings true with the Universalist agenda and the hope that all of our "heavens" are the same. In season 4, it was proposed by one character that those who had gotten off of The Island were in a place like Heaven - this was an early attempt to prepare us for the end when this turns out to be true. And in season 1, The Island is a strong symbol of purgatory as each character "moved on" from their old ways and started over with a new life.
I can handle this. Like I said, I'm a reasonable fan, and I can get over this boring stuff in order to get to the good part. So I kept waiting for something else to happen - waiting for some reveal that would make sense of the show. And I kept waiting. And then the credits rolled.
And that was it. There are no answers to the questions that have been raised. No resolution at all. Moriarty has stomped off to commit another crime and Sherlock Holmes is off somewhere reading Socrates. This is because the producers want us to see their message and want us to know that The Island doesn't matter, none of it matters, because we will someday "move on" from this - so we might as well go ahead and leave the mystery behind.
But the metaphysical ascension of the characters isn't very interesting - the Island is. So, why didn't they solve the mysteries that we care so much about? Did the producers raise so many questions just so we would all pack in and watch their religious message at the end?
I think they did - and that's pretty lame.
