I think I'm happy with the ending. Emotionally, it delivered, that's for sure. I loved the ending coming full circle with Jack closing his eyes after Vincent found him in the bamboo field. That was perfect.
I also think that we got all the answers that the characters figured out. That reminded me of what I liked most of the first few seasons: We were really connected to the main characters because we were as lost as they were, we only knew what they knew. Then, slowly, some went in different directions and we started being disconnected from them. That's why the middle seasons weren't as great. In the end, I wanted to know about Walt, why women couldn't have babies, what was at the center of the island to give it and Jacob all those powers but then the characters themselves never learned every mystery of the island. The goal was to get off the island and to kill Smokey. The finale reconnected us to the characters.
Some questions really don't need to be answered: Why Walt and Miles weren't in the church? Maybe they were still alive when Jack entered the church. Why were Walt's power not explained? Aside from the real life logistics, we were told that Walt wasn't what was expected, therefore, he wasn't Jacob's candidate. His story ended a long time ago even if we weren't ready to see it that way.
To tell the truth, I was very worried that the Island would all be a dream and that everyone would end up living happily ever after in sideways world. That would have been the Dallas Shower scene equivalent. So, in the end, Sideways world happens sometimes in the future, well after Jack died, well after Kate, Sawyer and the others left the island and made it safely home, lived their lives and died.
The only trouble I have really is Jack's son. The only thing I can figure is that Jack needed to see what kind of father he would be in order to come to terms with his own father which was the main thing that prevented him from letting go. Once he realized that he was more like his father that he knew but was still able to be a good dad, he made his peace and started on his way to letting go, seeing the light.
