Imho the scifi elements are just a stage for the drama.
At this point, most of the characters are intertwined with the mythology or the scifi aspect of the show. I can't see how they could easily seaparate the two.
And I don't really care what happens to the stage after the drama is over.
I don't think the mythology is just a stage, It's part of the story that's unfolding and I'm hoping that it gets a satisfying conclusion. For example, I do want to know what Starbuck is, why she came back and why she's important, or at least something along those lines. Just having her "reconcile with her dad" isn't enough. It would be for a show like Six Feet Under
, but not here.
