LAST EDITED ON 05-24-10 AT 09:37 AM (EST)I agree Michel. Jack's son bothered me too. The only thing I can think of is that Jack kind of "created" him to help himself work through his problems which is what I think you said as well.
As for Micheal and Walt well maybe they were not a part of Jack's heaven? Christian said these were the people that helped Jack during that time on the island which Jack felt was his greatest test. At first I could not understand Hawking with Desmond in this episode but I think she was concerned about him taking Daniel away from her little piece of heaven. Kind of explains also why Daniel, Charlotte, Miles, Lapidus were not in the church as well. This was Jack's story basically and who he needed to help him move on.
I loved the flashes in the sideways world. Never thought I was a romantic but apparently I am. Cried at every single one of them. Loved the island story. Thought it moved at a breakneck speed. Still a little unsure though of what Ben, Locke and Jack were doing with Desmond. Why did they lower him in the first place? I even liked Kate in this episode. Loved her realization that Jack was not leaving.
I also think that yes a lot is unanswered and it leaves me hopeful for other stories from the island.
Edited to add: Just read a spoiler on Dark UFO that they were trying to put out the light because it would make Flocke mortal so they can kill him. They did but had to restart the light so the island would stop sinking. I still don't understand why Flocke was going along with it? So the island would sink? Did he not know he would be mortal?
