Yeah, I don't agree with that either. It just doesn't fit with the storyline at all. But I'm pretty sure most people understand that the basis of the end of the show was the island was 'purgatory'(or something similar) and after they all 'die' on the island again, they go to 'heaven'(again, or something similar).
Here's some stuff I found about what was explained and what wasn't...not sure how much it helps really.
There are still a lot of unanswered questions. Did Lost Answer Questions?
(from the Lost and Gone Forever blog -- a list of "The Ten Big Questions" was compiled, and after the finale, the writer broke them down to see if they were answered to any degree of satisfaction)
10. Juliet and the Jughead – ANSWERED. I thought we would get this reveal early in Season Six – but as it turns out, it took until the final moments of the series before we got the real answer – The Jughead simply caused the Incident, just like Miles had predicted. It didn’t create an alternate timeline, it didn’t change the past, it simply reinforced “whatever happened, happened” – just like I had hoped all along. (Note: It also seems that a side effect was the transportation of our Survivors from 1977 to 2007.)
9. Adam and Eve – ANSWERED. Adam and Eve = Anti-Jacob and The Woman. Was it anti-climatic? A little? Was it proof that the writers had this whole storyline planned from the start? Hell no. Was it a question that was answered? Yes.
8. The Island History – PARTIALLY ANSWERED. More than any other question, this is the one that I wish we got a little more answers to. Yes, we learned how the Black Rock arrived on the Island, who built the FDW, and the history of Richard Alpert… which actually were the three things I specifically mentioned regarding this question in my original post – but I’m greedy and still want more. I didn’t need to go any further back in time to learn about the Egyptians (which would have undoubtedly come across as ridiculous), but I would have liked a little better answer about why it was such a bad thing if the Island was destroyed and what would have happened if SmokeLocke had escaped the Island. Getting these two additional pieces of information would have gone a long way in justifying everything that happened on Lost, and helping us understand the importance of the final battles between SmokeLocke and our Survivors, since we would know the repercussions of losing that battle.
7. Good and Evil – ANSWERED. Even though the answer was… there is no answer. As I predicted, things stayed predictably “gray” throughout the final season. Even when the writers went so far as to make SmokeLocke the “bad guy” by killing off a number of fan-favorites, they turned around and made his character totally sympathetic in the next episode by revealing what made him the way he was. The only disappointment here is characters like Ben, who flipped back and forth from good to evil numerous times throughout the last few episodes on a whim.
6. Jacob and Anti-Jacob – ANSWERED. They were two brothers, born on the Island, who became the Protector and Security System for the Island after some heavy manipulation by previous Protector, “The Woman”.
5. The Others – UNANSWERED. Yes, we spent some time at the start of the season in the Temple… which was a huge disappointment. But we never learned much about the nature of the Others and their society on the Island. Were they continually getting instructions from Jacob via Alpert? Did they develop the rules of their society on their own? Were they truly “worshippers” of Jacob who were acting to protect the Island, or were they a group of people being tricked by Anti-Jacob via Ben all along? What was up with the kidnapping and costumes from the early seasons? The writers had plenty of opportunities to answer these questions every season, and every season they decided not to – which means they didn’t know, didn’t think it was important, or wanted to leave it intentionally ambiguous to let the Others be whatever we wanted them to be. Disappointing.
4. Fate vs. Destiny – ANSWERED. Jacob brought our Survivors to the Island to become candidates to replace him, because they were all individuals who needed the Island as much as the Island needed them. Although I still think it would have been cooler to find out that Jacob didn’t know much, and was retroactively evaluating his candidates based on who accidentally ended up on the Island, the body of evidence seems to point to the opposite – Jacob was a flawed individual who “pushed” characters in a way to bring them to the Island. He wasn’t perfect – his actions resulted in the deaths of hundreds of people over the years (at least), but he brought them to the Island. It wasn’t just a coincidence.
3. Smokey – ANSWERED. We didn’t get the “nuts and bolts” answer of what Smokey was made of, but most of us didn’t want that anyways. We learned that Smokey was SmokeLocke who was actually Anti-Jacob, who turned into Smokey after being thrown into the heart of the Island a long time ago. There are still unanswered questions about why the ash and pylons kept him out, why he killed some but not others, and other miscellaneous “rules” that would have been nice to find out – but we got the big answer.
2. The Funky Island Stuff – PARTIALLY ANSWERED. We got answers to the Numbers, Richard never aging, the Sickness and the Whispers… and a lot of people thought they were lacking. So maybe it’s for the better that we never got firm answers to the other items in this category, like the time travel, moving the Island, random appearing and disappearing of Others, etc. More than any other question, I’m okay with leaving some of this stuff unanswered. The Island is a mysterious place where magical things happen – to find out exactly why takes away some of the “magic” from the equation. But like most, it would have been nice to get a little closure to the Aaron / Walt storylines from the early seasons.
1. The Fate of the Survivors of Oceanic 815 – ANSWERED. The most important question of all, and one that was totally answered in the finale. In short, they die. We all die, eventually.
*Jack sacrifices himself to save the Island (and world?).
*Hurley becomes the new Jacob, Ben becomes the new Alpert.
*Alpert, Kate, Sawyer, Miles, Claire, and Frank escape the Island on Ajira 316 to live out the rest of their days in the “real world”.
*Sun, Jin, and Sayid die on the Island.
