Lost and Found
The Lost finale answered all our questions, explained every mystery, and made the 120-plus hours of view time all worth it.
The final scene with the majority of the cast fading into the light resulted in a collective "What?!" There may have been no way for the creators to tie up such a tangled mess without creating a bigger mess, but despite the thematic implications, it was cathartic to essentially rewatch a highlight reel of the character stories that made Lost so appealing in the first place.
The show's creators insisted this was a character show all along and they stuck to that in the series ender.
Forget the physics and the Lostarcana, what dominated the finale (at least the part we can make sense of) was a half-dozen love stories: Sawyer and Juliet, Sayid and Shannon, Sun and Jin and their daughter Ji Yeon, Charlie and Claire, Jack and Kate. For all the dramatic, sweeping violin music, the remembrance scenes never failed to be touching.
"You All, Everybody" indeed.
Was the island just a Unitarian version of purgatory? With the wreckage on the beach as the final image on screen, it certainly seems like it. Don't ask us what that makes the sideways reality, though... or the role of Jacob, Ben, Desmond and Jack.
Some questions are better left to greater Lost philosophers.
