Yeah, good finale but they left so much unanswered. I understand they want to leave some things a mystery, for whatever reason, but after seeing every episode over the course of six years I was still left with a bunch of questions. The backstory of Jacob and Smokey's 'mother' is never explained, the energy pockets, time travel, Desmond's unique abilities, Hurley's and Miles' commune with the dead, how Whidmore or Elly originally find the island, the origin of the light @ the center of the island, how Dharma/Degruttes/Hanso got involved, how the others originally got to the island, etc. When Desmond pulls the rock out of the hole and Locke hits Jack in the head with the rock, why doesn't he finish him off? Clearly he is allowed to kill any protector of the island other than Jacob (when he was alive), and Jack gets the jump on him minutes later b/c he didn't kill when when he was unconcious. What was the origin of the temple and what was Togem doing? What was the true origin of the numbers? When the numbers weren't entered by Locke and the hatch imploded, if Desmond hadn't turned the failsafe key...the world would have actually ended? By what means? Why weren't Desmond or Jack turned into smoke monsters after entering the light and water (maybe b/c Jack was already protector, but Desmond? His resistance to electromagnetism?) The flashes sideways...now that they all had Deja Vu, is that reality occuring as well, or is it simply a glimpse into what might be? The end, where Jack reunites with his father in the church, was deeply moving for me. My father is gone and I can only hope he's there to greet me when my time comes. That would be something.
