This terrible, emotional path is exactly what the series needs as an endgame. Characters who have changed (Tigh, Lee Adama, and others) are finding their reversions and revisitations to earlier times (sorry for the vague natures, trying to avoid spoilers).
The sadness, helplessness and hopelessness that the entire fleet faces upon their arrival at "dead" Earth is addressed, and although it takes a back seat to the major plots of this episode, it gets its due representation.
I was skeptical about the new season, but I have in no way been disappointed. While the "Final Cylon" answer has been given, the allusions to future episodes promise to keep the intrigue alive.
