Wiggs, I agree about the characters, not the circumstances, carrying the show... Amen. But I felt the end was the Island's story and not the characters. It did not really matter what the characters did in life... the Island represented a universalist theology that I strongly disagree with. Murder, treachery, torture, lust, greed, selfishness, etc. (i.e. the aspects that made the characters interesting) seemed to be overlooked if the characters were part of the "in crowd."
I felt like Ralphie in A Christmas Story... "Be sure to drink your Ovaltine." The very ending made the entire series appear to be a commercial for moral relativism and universalist theology. Maybe to Lindeloff and the other writers this was a great ending. Obviously, I don't represent everyone... one of my friends loved it. He was not bothered by the end, but the process. For him, the struggle was all important...
Jack, Locke, Michael, Kate, Eko, Charlie, Jin, Sun, Sawyer, Hurley, Ben, Rose, Richard, Cooper, Desmond, Sayid, Miles, Widmore, Eloise, and Rousseau are great characters. I got to see multiple sides of each character... and I often identified with the dark side after I already sympathized with the good side. Great writing. I could write pages on their motivations, their secrets, their failures, their victories, their soft spots, and their hidden agendas. But the search for validation/redemption/peace for each character was paramount... I loved that about the series from the pilot.
But I know I can't win an argument against you because all you have to say is Pack 21, Bears 14, and I'll cry.
