I found it a great end to a great series. I had never expected the end to answer all those unanswered questions. I thought that I would be pi$$ed off that I wouldn't be getting all the answers but I'm not and it ended perfectly for me. The very Lostesque ending was solid and all those unanswered questions didn't really matter anymore. So that's it. Some ramblings:
The "gathering place"/LA makes sense now. Their "lives" were still related to their real lives (Kate still a fugitive, Sawyer still seeking out Sawyer) but in the flash sideways world, their lives were better.
Locke and especially Jack, who was the last one, finally "let go" and were able to move on.
Mrs. Widmore with all her knowledge, which will never be explained. Now I know why she was upset when the prosepect of Daniel leaving with Desmond was a possibility. I guess she is enjoying spending time with her son in this place before she can move on (probably feeling guilty about what she did to him when they were alive!)
Ah, Ben is the new No. 2 and assumed a Richard-like role. I was expecting that.
Now the only question that I do have is how did Hurley and Ben return Desmond home? Ben said that there was an easier way.
Michael Emerson saying that he was the most beaten character in TV history - word!
The various flashbacks between the characters had me tearing up!
Finally, the very ending with Jack and Vincent and Jack's eye closing instead of opening... very emotional.
