To sum up, it was all a dream people had in purgatory after they had died on a magic island.

That's what I got from it. I figured the fact that Jack died in the same spot he woke up, and the first scene was so perfectly mirrored, that it was definitely all just a dream. Remember the terrible wound in his side in the pilot that Kate stitched up? It seemed to reappear as he was stumbling through the forest. Hm.

I don't see why only the main characters were in the church at the end. What about Artz, who was blown up by dynamite? What about the two douchebags who got buried alive? Is it evidence the writers had no clue what they were leading up to? Probably.

Also... if everyone came to the Happy Shiny Funeral Home no matter when they died, why did everyone happen to be the exact same age they were on the island? And why was Aaron a baby? Maybe he lived eighty years, died peacefully in his sleep, and now he has to spend an eternity as an infant because that's how fucking Jack Shephard knew him? What?

Anyway.

And one glimpse of Evangeline Lilly was enough to remind me why I spent so long on this show. :D
