THE DUST SETTLES

“ An old error is always more popular than a new truth. ”
— German Proverb 

Dust is the accumulation of eroded, ground, atomized, broken down and dispersed elements of dirt. As we have ground through the full rerun cycle of Lost, what has been settled?

Not much. Subjectivity of the subject matter is still a personal opinion.

What were the major themes from season to season?
First, it was all about the crash survival and rescue.
Second, it turned into survival against a smoke monster.
Third, it turned into a cat and mouse game of combat with the Others.
Fourth, it turned into the survivors re-living their secret pasts and distrusting each other.
Fifth, it centered around a mysterious overlord named Jacob.
Sixth, it concerned "saving the world" from the invasion by Widmore's men.
Lastly, it was a battle between Jacob and MIB over the guardianship of the island powers. 

Did the 815ers survive the crash? Two schools of thought on that one: yes and no.
Did the 815ers find rescue? It depends if one thinks figuratively or literally.
Did the 815ers survive the smoke monster? It depends on what you believe the smoke monster(s) represent.
Did the 815ers survive the game with the Others? It was kind of a bloody draw.
Did the 815ers learn to trust each other again? In the final island season, the answer was no - - - deep seeded personality conflicts remained as tension between characters.
Did the 815ers find out about who and what Jacob was/is? Besides the short candidate's campfire in the final episode, no one really knows what Jacob is/was or represents.
Did the 815ers "save the world?" There is no evidence that anything that happened on the island had any bearing in the real world.
Did the 815ers have any significant role in the battle between Jacob and MIB? Since both Jacob and MIB were immortal beings, their own demise was of their own choosing . . . the characters actions were manipulations by the island gods.
