I thought that the finale was emotionally very satisfying. I think the true meaning of the word 'Lost' was always about these peoples souls, and never about where they actually where. As a finale to a character study, I was very happy where they all ended up.
The series has made me feel many emotions over the years, such as why even successful and fortunate people can end up feeling 'lost' and unhappy in themselves and their lives, and how the choices and decisions we make can affect who we are so massively. I loved that the series was left on an optimistic note with regards to redemption. It truly is never too late to make amends, or to change your situation.
I am kind of glad that there is so much mystery still left unexplained, which leaves it consistent with the show as a whole. At the end, what mattered was the time that these people spent with each other and the things they experienced together, which is ultimately what I feel matters in all of our lives.
If you have the time, there is a fantastic video on
Youtube where the creator JJ Abrams talks about a box he was given as a kid, that contained something inside of it. He has never opened this box over all the years he has had it, as he says that the mystery of what 'could' be inside it is more interesting and inspiring than what probably is inside of it. This was the whole starting idea for the show, and I would really recommend giving it a watch.
On a side note, I feel that the acting in the finale was outstanding, and everyone really upped their game to deliver a great farewell to their characters. Sawyer and Juliet at the vending machine particularly comes to mind.
