Did some googling (still doing it) to see what others are saying. I thought this was pretty cool:

As early as the first season, there were suggestions that no-one survived the plane crash and the island was some sort of purgatory.
Close but no cigar. The island was real and as Jack's dad Christian Shephard ( ... Kate was the one that spotted it. Really how did we all miss that one?) pointed out "everything that happened, happened".
Instead, we learned that rather than being some some kind of alternate-timeline, the flashes sideways were glimpes of a kind of limbo between life and death.
In their deaths - some on the island, some much, much later - they were all pulled together to move on to the afterlife.
The people that meant most to them during their lives would be there with them as they moved on to the next plain of existance.
With various philosophies running throughout the entire series, the final scenes took place in a multi-denominational place of worship.
Lost fans attempt to explain the programme's plot
There were some genuinely moving touches, Ben remained outside the gathering, not quite ready to leave his own personal purgatory and forgive himself for his sins.
Yet Locke did offer him gratefully accepted forgiveness and Hurley, who invited Ben into the gathering said he was a "good number two", with Ben telling Hurley he was a "great number one".
We were left to assume that the two men acted as protectors of the island for some time.
It ended as it had begun with Jack lying in the same bamboo forest in which we first met him in episode one. Back then Jack opened his eyes for the first time on the island, this time around he closed them for the last.
Yes, the finale could be accused of being a bit melodramatic and certainly there were many issues left unaddressed.
Whatever happened to Michael and Walt? What was the significance of the Egyptian statue on the island? What about the temple? Why, at the beginning of this series, was the island underwater?
Discussions will likely rage for years to come but if there is any lesson from the final episode, then it is that sometimes you just have to let go.
I like the way they worded their explanation of Ben. That helps some.
