Of course. The story didn't end after Jack died.
Life did go on, and time after time one of the characters died, even Jacob-Hurley.
And their "souls" collected in the "sideway" to meet a last time and to move on.
Best Lost ending ever, i loved it!
Well, I still really want to know more about Dharma, who built the cool island stuff like the light room and why the island exist, but I guess it really isn't important in the scope of the series.
