I thought that was a pretty easy-to-understand finale to Lost.
I don’t get why people say they’re still confused or whatever.
**
With Jack’s dad there, and their conversation leading to the conclusion that Jack is dead, obviously, they’re in purgatory.
You can have whatever label you want, purgatory, limbo, or anything else, but essentially it’s post-death.
Obviously.
A bunch of dead people are there.
Plus, Jack’s dad pointed out that everybody’s got to die / go sometime, so DEATHDEATHDEATH.
Since Jack’s dad also pointed out that the sense of time where the two of them were is screwy, obviously, purgatory does not follow the rules of physics.
OR
They simply all got there at different times.
Either way, they are all dead, everybody in the church.
Jack died at the island, and everybody else died whenever they died, whether they got off the island or not (whether or not the people in the plane landed safely is irrelevant; the series is about the island, not the outside world).
Now that everybody is dead, they are going to want to meet up again with the people that made the biggest impact on their lives: the people they met on the island.
So, like Jack’s dad said, they created this purgatory place, consciously or not (although the knowing of the need to go to church and to get the other island people and of satisfaction after their memories came back showed that it was probably a conscious decision after death), so they could gather after each of them were finally dead.
Sideways-Universe was a purgatory-type “waiting room.”

I thought it was the easiest thing to understand ever.
What other unanswered questions are there?

Where was Walt? What was the deal with his powers? What made Michael unable to kill himself? Why did the light turn the man in black into the smoke monster but not Desmond or Jack? Jacobs “mom” said that he couldn’t go into the light or it would be a fate worse than death. It didn’t affect either of them! Why could some leave the island and not others if it was jacob’s rule that noone could? All the end did was explain the flash sideways but nothing about the island or the powers of Jacob. And why could hurley see dead people?

Thanks for reading!
Wicked awesomepants, a comment, thank you, finally.
Walt – Is still young, so he’s probably not dead yet… So of course he wouldn’t be in purgatory.
His powers – I don’t recall… Powers… Hm thinkthinkthink
The suicide thing – He wanted to kill his dumb self because he thought he couldn’t be forgiven for his actions, so when one of the Others (AKA weird people from the island) offered him redemption, no need for the emo-ness.
Smoke Monster – We don’t know what turned him into the monster de la smoke. Maybe he was born that way. I dunno.
Jacob’s mom – Yeah, the island getting destroyed is the fate worse than death.
Jacob’s rule – Apparently the thing being moved out of the hole (that’s what she said?) put the rules of the island, so Evil Locke / The Smoke Monster / Man in Black could be killed, and people could leave.
That second-to-last thing you said is very true. Lost as a series makes little sense, but I feel like the ending itself was completely understandable. I don’t understand the series, but I understand the ending. The ending didn’t explain the series, but it brought the series to an end. And it explained the super most non-understandable part: flash sideways.
And Hurley is Jesus.

lol.
